Even the nook's own "authorized" charger wouldn't be usable by default - you'd have to cut the data lines in the wires going there to make the USB usable for data while it's connected, at which point it would no longer be detected as a high current charger. That's why I'm suggesting the charge mode would need a software override.

So I've heard, yet I've had persistent problems with both 7.02 (the only CM version thats proved usable) and the official nook installation - either of these on the emmc seems to break often when I do anything with alterantive installs on the sdcard. It's very puzzling. I suspect either there's a widespread bug that's rarely triggered and so overlooked (but happens frequently for me) or there's something flaky about this particular nook. I keep meaning to look into writing some sort of uboot memory test routine...

Nonetheless, being in the mood for a fresh round of tempting fate, I just made another backup image and am about to trade out that sdcard for a 16g sandisk class 4 with nightly 87, preparatory to trying your usb kernel.

Installed nightly 87 by itself, let is sit for 10 minutes. To my surprise it came alive when I pushed the N key. But not for long. Opened and closed status slider. Tried to launch browser - no repsonse. Tried again - it's hung. Logcat shows the runtime is stuck in an infinite restart loop... this is pretty much what always happens.

No need to mess with fedora or other distro unless you want to.

Thanks everyone, this is amazing. I will let you know when my hardware arrives and I get some free time about maudio usb, but again I am not hopeful.

Does this mean that it could be soldered?...can I reference pictures? I don't have the tools to do so, but my mother is certified in all types of soldering (including BGA/smt etc.) and has all the tools at work, I wouldn't mind trying it on mine...and having her do them for a few of us...
[Nook Color Android Development] verygreen:
There is no schematic provided with Nook, so it's a bit hard to guess where to solder it to. But you can lookup the twl chip reference on the TI site and try to figure out which pin is the one we need.
[Nook Color Android Development] FRSP:
Lots of mysterious crashes in getting nightly 87 installed before it decided to be semi-stable, but I am typing this into a nook from a usb keyboard...
[Nook Color Android Development] FRSP:
I can't really conceive of opening up nooks and soldering on them being superiour to a software solution. Adding unrouted signals to a bga is pretty much not done - even picking it up and putting it down again is tricky (we used to have the machine at a previous workplace, and I watched the salesrep demo it with a bga, but we never actually used it for anything more challenging than a QFN with a hefty powerpad underneath)
[Nook Color Android Development] seth.i.simmons:
Just tried this, and I can get N87 up and running fine, but for the life of me, I cant seem to get your kernel to install... It justs boots right up into N87 on my SD card, and doesnt even go to the install screen. Anything I need to do special to install it?? I'm just placing it on the boot partition, and putting it in the Nook, and it just wont install. I've tried re-downloading and reinstalling the installer image and N87, and cant get it to work.

Thanks in advance VG!
[Nook Color Android Development] verygreen:
Installation happens if you boot into recovery mode. See installer instructions on how to trigger it.
[Nook Color Android Development] ADude:
Verygreen -

There are two of us in the thread interested in the concept of Audio Input, since the NC has no microphone, so what do you know about that possibility (since USB makes it more practical) ?

Thanks !

I will totally buy a webcam w/ microphone to test if it is possibly possible to get working.

[Nook Color Android Development] nolook:
it would be so awesome to get skype video calls to work...i have the ps3 eye camera now on my laptop...
[Nook Color Android Development] :
Yeah, don't get me wrong. This thing is amazing, and I do feel like I may seem ungrateful at times, but I am just asking. If they devs tell me to f off and never come back, I would do so gladly :P

Just wanted to make sure I'm not missing the "access code" to the webcam. I know a 3 MB limit of the kernel was a concern, but I thought the new bootloader/MLO fixed that. In any event, I would just like to try out the MS webcam and a BT headset for voice calls (GrooveIP freezes when I try to switch to BT...anyone have ideas?)

To verygreen/fattire/dalingrin/et al. You guys rock (as you should know). Thanks for everything.

I bought Null Keyboard v2 and downloaded the demo version of BlueInput. Null Keyboard v2 a paid app was suppose to prevent my virtual keyboard from showing up. It still shows up. BlueInput is suppose to find HID devices. It only found my "BlueTooth Laser Travel mouse" and not my Xoom bluetooth keyboard. However for some reason I can now use them both concurrently!!! Only had 1 lockup in over 3 hours of use!!!

The only thing I don't like is when the keyboard goes to sleep, I have to press and hold the power button for the light to come back on and it to reconnect. The Logitech bluetooth mouse does not appear to have as many problems with sleep althought it will stop and it takes me a little bit of playing with things to get it to work again. But no lockups!!!!

Do all you people using only the bluetooth keyboards have it go to sleep and you have to wake it up after periods of non-use? Anybody have any ideas what these apps changed that stopped my keyboard sleep issue from locking up my mouse and thus locking up the nook? Neither of the apps are actually working as advertised but I can not complain as whatever they loaded in overrode the lockup problems I was having before.
[Nook Color Android Development] Moshe5368:
I do have sleep problems with the logitech keyboard after periods on non use. I find that Sometimes, I have to go to bluetooth settings and reconnect the keyboard but other than that, no issues. Never had a screen lockup using the kbd and mouse both. It seems that the logitech kbd sleeps after a period of inactivity but seems to have issues reconnecting automatically. Not a major problem but it bugs me just the same.

What is everyone using for an adapter to connect their USB devices? I have been looking for a short (6") cable with a micro USB male on one end and a standard female USB on the other end. Haven't found much out there yet.
[Nook Color Android Development] Moshe5368:
I had a male mini usb to female usb but can't remember where I purchased it several years ago. The only adapter I have found recently (and the one I use) is the micro male to female usb through amazon. I would prefer one with a flexible cord as that would allow me to keep the nook in portrait mode where I am usually but until I can find one I just use this rigid one from amazon. I did hear of someone finding one online through some chinese source but never found it myself.
[Nook Color Android Development] :
I bought a small one off ebay for $1 shipped or so. I was at the Dollar Store the other day, and I actually saw a cable that would work there!

http://cgi.ebay.com/Standard-USB-2-...238331?pt=PDA_Accessories&hash=item1e64cdf5fb

Only you can get it a LOT CHEAPER if you look harder than I did :)
[Nook Color Android Development] Arbelzapf:
Great news :) I don't have one, but I always wanted to pick one up.
[Nook Color Android Development] patruns:
Thanks guys! I ordered that one off ebay. It is cheap enough and free shipping so if it doesn't work, nothing really lost. My coffee this morning cost more..... :D
[Nook Color Android Development] Moshe5368:
Let us know how the adapter works. I find new uses for the nook daily. Being retired gives me lots of time to play and find new and exciting ways to screw up things around the motorhome. On the plus side, the nook keeps me out of trouble by giving me things to do besides "improvements" to the coach....

cable issue

I'm also playing with the USB stuff, however today my kitten decided to chew my Nook USB cable so I can't fix it. I connected my Nokia cable to the power adaptor and it works, but the charging is really slow.

Someone mentioned here that there was a workaround to fix this and to enable full-speed charge even with non original Nook cable. Anyone got any links or info please? right now it takes ages to charge the nook.
[Nook Color Android Development] newellj79:
I think efforts where abandoned.
[Nook Color Android Development] Dj-Gutz:
Could you charge at full speed with the original cable connected to a powered hub?

I'm sorry for the wierd question but my cable is defected and I wanted to know if it worth fixing it since I'll be using usb-host all the time
[Nook Color Android Development] Moshe5368:
The factory nook cable uses 2 additional pins within the connector to enable fast charging. There was talk about trying to short pins through the connector to enable fast charging with a home made cable but, believe me, you really want to get a replacement cable from B&N. It's much safer for your nook and the charge rate is much faster. I am not an electrician nor do I want to take chances with this wonderful device. B&N should be able to get you a replacement cable asap. Give them a call or stop into their store. Many people here have said they called B&N customer support about broken cables and B&N sent them a free replacement. Just sayin......
[Nook Color Android Development] newellj79:
I had one sent a while back. Just tell them the "n" on the charging cable turns red when plugged in and nothing happens. At least that is what happened to mine. I think my 9 month old got hold of it to chew on.
[Nook Color Android Development] lschroeder:
When using usb-host with a powered hub all the time how do you or anyone else handle the charging issue?

I found that when playing flash websites or flash and mp4 apps I like to have my original "n" cable plugged-in and connected to the original ac adapter so as to keep my battery fully charged. Any way to do this with a usb-host enabled?

I bought a y cable for the powered hub, but the only way I found to significantly charge the nook using the y cable was from Nook Tweaks to toggle off the USB Host mode. With USB Host mode and External VBus both checked the charge was so small that most any Nook activity was larger then the charge and thus the battery percentage was always over time decreasing. Is that what everybody is finding?

With the y cable it does not matter whether I connect the power leg to my hub or with an extender to my original adapter or other usb power adapters I own. I still get no significant charge with both Nook Tweaks options checked and my upstream leg connected to the powered hub with usb devices connected.
[Nook Color Android Development] Dj-Gutz:
Thanks lschroeder! that is exactly what I asked

Since my NC will be mounted in a car and will be connected to usb-host all the time...

Can someone else confirm you can't charge at full speed with usb-host and vbus ? or someone maybe got it working?

My cable ( or charger ) got a unique problem , it isn't broken and it does charge

but only sometimes at full current ( you can view my post on the "nook charger mode control" thread )

I live in Israel so to get a replacement will take a long time , which will probably delay my project - and if it doesn't really needed I can install anyway and get a replacement at my own free time..
[Nook Color Android Development] lschroeder:
I read your post over at the nook charger mode control thread. Another issue you need to be aware of is that spare parts show voltage increasing while reporting discharging as well as icons in status bar reporting incorrectly as well. Verygreen said he needed to fix this but I don't think it has been yet.

Using spare parts, my original "n" cable plugged-in and connected to the original ac adapter by usb extension cable, says Charging (AC). My original "n" cable plugged-in and connected to the original ac adapter by female to female adapter y cable power leg, says Charging (USB). Note: not using Nook Tweaks or powered hub for this information.
[Nook Color Android Development] Dj-Gutz:
I'm not really counting on spare parts or any other parameter on the system ( I know it's sometimes gives false data )

The charging rate is about 10% an hour ( which corresponds to 500ma )

Can you check with a powered hub connected to the original cable your charging rate in deep sleep?

BTW , Thanks for the extension part , it will help me to diagnose if the d+/d- short is really the issue with my cable :)

Edit :

I seem to have another ( wierd? ) issue

My powered hub only recognizes devices when its unpowered

This is the hub I'm using :

Can there be a power issue between the nook and the hub?

DMESG shows absolutly nothing about the usb except "charging is enabled/disabled" , and yes I tried restarting/messing with nook tweaks enabled and disabled - nothing seems to work

I see some people use a y usb cable , is it necessary? cuz I just plugged in the external power to the hub's power plug
[Nook Color Android Development] NCKevo:
Has anyone tried to use a USB-to-VGA adapter? Either on the nook or on android in general? I've found a few links online and was thinking about picking one up and trying this out, of course any pointers would be useful :)
[Nook Color Android Development] gallahad2000:
there's 2 types of those: 1.external video cards: don't believe they're supported by android. 2.device specific or MHL video out (usually RCA or HDMI) cables: NC doesn't have MHL support that I know of.

Type1:http://www.cablestogo.com/product_list.asp?cat_id=1525

Type2:http://www.connector.cn/english/ProductView.asp?ID=675&SortID=249 or http://www.amazon.com/OEM-HTC-Out-Cable-ACT100/dp/B002OOZDSE
[Nook Color Android Development] NCKevo:
Yeah, I found this thread;

http://xdaforums.com/showthread.php?t=1061856

Which seems to indicate that one can use usb host to connect to displaylink devices and then use the driver from;

https://sites.google.com/site/voyageofbeagleboard/Home/displaylink-for-android

to get them working.

And there's also this app https://market.android.com/details?id=de.killig.framebuffer, but I'm not sure if it requires the driver mentioned above or not? Not quite sure what to make of all this / what is needed, etc.
[Nook Color Android Development] :
Mine's the same way. Unpowered it works fine, powered the NC starts acting really weird.
[Nook Color Android Development] newellj79:
Same here. I have the same one too.
[Nook Color Android Development] Dj-Gutz:
OK at least its good to know I'm not the only one :)

Now lets figure out the problem

Maybe its the power distribution of this specific hub

Anyone got a different powered hub that works?

Anyone managed to use this specific hub with external power connected to it? How?
[Nook Color Android Development] gallahad2000:
You'd likely have better luck by getting a DLNA adapter and wirelessly sending video to the monitor or TV.
[Nook Color Android Development] Moshe5368:
I have been using a Belkin 7 port powered hub for all my applications with no proble. I don't know anything about sound and video applications as I do not use them with the nook but eveerything I have tried with the belkin hub has worked. This is the belkin model FSU237 hi speed 2.0 powered hub.
[Nook Color Android Development] lschroeder:
I think deep sleep is only available when not plugged into ac or usb power source.

When I put it in sleep mode, hub powered up, with the original cable going to female to female adapter then to upstream port of hub (male to mini male) it does not charge. Nook symbol is not on. when I switch it to y cable with power leg plugged into device port nook light turns yellow, spare parts, says usb charging. If I leave in sleep mode it will eventually reach 100% and turn green. Same it true if I plug power y leg directly into nook ac adapter, usb charge only, no ac charge.

This thread has lots of info usb cables, adapters, connected to the nook

Awesome work. Just tried a silicone roll up keyboard from Fry's, works fine, tested a USB stick too. Works great.
[Nook Color Android Development] Dj-Gutz:
Thanks but the cost of it with shipping to Israel is overwhelming ( about 50$ )

Do you have a cheap hub I can get off ebay that worked for you?

So it's a no-go on the 2A through HUB? even using the original cable?

I read the thread and it only applies to charging not using the usb-host feature ( which is a must for me )

I already ordered a DCDC-USB power supply for the car that puts out 10A so the current will be available

Too bad there is no way ( at least not that I know of ) to charge at full speed connected to an hub
[Nook Color Android Development] lschroeder:
A no-go on the 2A through HUB is what I have found so far. I know the other thread only applied to charging put I think we have the same problem as the charger in trying to get 2A without nook adapter, nook n cable, directly connected. Maybe a special y cable where the power leg has pins shorted and is connected directly to ac adapter or the dc adapter availiable only at BN site. I just ordered this special auto adapter for nook color at BN site as it seems that from a car lighter socket it is the only way to get 2A.
[Nook Color Android Development] DigitalMD:
"So it's a no-go on the 2A through HUB?"

Any properly built USB hub is going to probably only supply a max on each port of about 500ma as specified for USB 2.0. It does not matter how much input current you have going into the hub. Here is a somewhat dated artical that has some interesting USB power information.

http://www.girr.org/mac_stuff/usb_stuff.html
[Nook Color Android Development] Dj-Gutz:
Thx for the article

What about connecting the nook with the original cable + male-female extension with power wires connected directly to the power source

Will it work?
[Nook Color Android Development] DigitalMD:
Which power supply? I kind of doubt this setup will work at high charge rate because it probably does not power the extra wire / pin that Nook uses to increase the chrage rate, but I have never tried it, so its worth a try. Won't hurt anything just to try charging and see if the high rate works.
[Nook Color Android Development] residentorca:
I tried using a Plantronics USB headset and the microphone input worked but the sample rate was not compatible (as I believe has been reported earlier). The resulting pitch of voice through the mic was several octaves too low and was slowed down, like playing a 78 rpm record at 33 rpm.
[Nook Color Android Development] Dj-Gutz:
The power supply is on the way ( DCDC-USB )

http://www.mini-box.com/DCDC-USB

I'm hoping to do some tests on the next few days cuz I have a friend who is going back to the US and he can get my cable replaced and ship it back to me

Just need to get an extension I can cut and mess with :)

But , I saw some posts here about using DSLR with USB-HOST and I thought some of you would be interested in making this work for the nook ( too bad the BETA is a paid app for now ) .

I don't have a DSLR so I didn't test this app.

Has anyone tried connecting their nook color to their phone via USB to tether?

When i am in non-wifi covered areas, ive been switching on wireless tether on my nexus one and nooking from there. But this drains heaps of battery, usb would be neater.

I am interested, but do not like the idea of experimentally plugging my two and only android devices into each other...
[Nook Color Android Development] Dj-Gutz:
I've done a few more tests I wanted to share and get your opinions

First I managed to overcome the high speed problem I had with the Charger Mode Control app for some reason ( thx verygreen ) , so it must be a software issue I'm having

Verified with a DMM and Battery Monitor Widget

As soon as I press the ON button , charging current rise to the normal level - OFF goes back to 500ma

This worked for me with the original charger and a power supply with d+/d- shorted using an usb extension cable ( this is all with the original nook cable of course )

Couldn't make it work with a standard micro usb cable :\

As for the powered hub issue , I tried all sort of things such as connecting an usb extension with only the data wires goes to the hub and power comes from a different source and not the hub

Nothing worked , when the hub is powered the nook doesn't even recognize it ( this is using a standard micro usb cable , the original cable for some reason doesn't even work with the hub un-powered )

It's really weird cuz when I connect the power to the hub while the hub was working non-powered it's still works and the usb devices still connected ( but its not charging even with VBUS enabled )

Only if I press enabled/disabled in nook tweaks it gets un-recognized

I would love if someone else can confirm working with any powered hub when its powered ( preferably one I can find locally )

I'll probably order the Belkin someone recommended earlier , But I really want to make sure I don't spend 50$+ and 3 weeks for something that won't work

I do have a DSLR, but I can't get Market to allow me to install it. I tried modifying build.prop to have Market think the NC is a galaxy tab, and that didn't work. Apparently the big thing here is whether or not this USB host mode has "android.hardware.usb.host" enabled. Does anyone know? This is the primary thing this app requires in order to be able to install it.
