I ordered a cheapo. Ill let u know how it works in 3-5 days :)
[Nook Color Android Development] verygreen:
BTW speaking of conversions and such, I was just reading some vendor libaudio code and they do manual rate conversions.

The good news is that I think I can reuse that conversion code and hopefully we'll have mic input working perfectly soon.
[Nook Color Android Development] newellj79:
Hell to the yah!
[Nook Color Android Development] botossi:
great news vg! good luck to you and us all ;)

I noticed for the Motorola Zoom there are a couple of NTFS mount apps out there. Has anyone looked at those or tried them with our setup?

https://market.android.com/details?id=au.dach.drivemount
[Nook Color Android Development] dalingrin:
I can make NTFS work soon. I need to get my USB adapter first though. I'll be out for next week but after that I'll figure something out.
[Nook Color Android Development] TheAmazingDave:
I found my old Pharos GPS-360 USB receiver that came with MS Streets and Trips 2005. Its label indicates only 70mA draw so I figured I'd give it a shot. According to dmesg, the device is under the current limit and is recognized by Android as a serial device. Any way to actually use this? I assume I need another program like what is used with BT GPS receivers.
[Nook Color Android Development] DigitalMD:
You're the man............

Thanks
[Nook Color Android Development] verygreen:
Just like with BT GPS devices you need one for the usb one as well.
[Nook Color Android Development] newellj79:
Freaking crazy. Where did u learn to do this? Seriously, I'd like to know.
[Nook Color Android Development] lekofraggle:
Yeah, as I expected, that's what happened with my maudio card. All lights no sound. But, you are right, even in osx you need drivers for it. I was going to search around for how to use it in linux, and then maybe try to port the library, but did not and may not get around to it. For real recording, I want my computer. For simple live recording, I have my phone. Two tracks would be nice though.

~Leko
[Nook Color Android Development] lekofraggle:
Nice. I found out last night (typical of BNs QC) that one of my nook cables supports my vivitar reader without a hub, and the other flounders. The light begins to light, and then just flashes. It does this even with an sd card.

Be careful with those autounmounts. I think they can hose your data. That is why I stayed on the old nightly. With the manual mounting via terminal, this is flawless.

Have fun.

And, know there are a few raw converters coming up too.

~leko
[Nook Color Android Development] TheAmazingDave:
Thanks VG, that's what I thought.

A Google search reveals lots of info on the topic. My Nook refuses to communicate via ADB so I haven't tried it myself yet.
[Nook Color Android Development] skwalas:
I guess random auto-unmounting can be considered a bug, if only occurs with the auto-mounting setup. Dalingrin and verygreen, think you could take a look at this at your convenience? No idea how prevalent it is, but both leko and I are experiencing it under the same conditions. Would be interested in knowing if others are experiencing the same?
[Nook Color Android Development] lospulpo:
Hey, I have an SNES to USB Converter. I was trying to get it plugged in here but I can't seem to get any of the emulators to recognize input. Is there anyway to check if I'm plugging it in right?

Just going to Nook Tweaks > USB > and checking the Host Mode box then plugging in.

Tried checking the VBus box as well. Any help is appreciated.

When I plug it into Windows it shows up as Standard JoyPad driver I believe.

Help

Guys, i can mount and see the content of microSDs using a USB Dongle, but when i try to access my PEN DRIVE 8GB Kingston nothing happens... any clue?

Just regular cable + female adapter

Using n136 + Nook Tweaks....
[Nook Color Android Development] bradputt:
many thumbdrives doesn't work, they draw too much power.
[Nook Color Android Development] lschroeder:
I have the same problem with ADB. Did you try adbWireless (Widget version) by MrSlir? I use it all the time.
[Nook Color Android Development] botossi:
Thanks for the heads up! is there a confirmed one? a specific brand/capacity?? thanks again!
[Nook Color Android Development] Dj-Gutz:
botossi -

I couldn't get my sandisk cruzer 8gb ( removed u3 ) to work with a female-female adapter ( it should probably work with a powered hub )

this is the one :

Though the partition is NTFS but the orange led didn't even light up so I haven't tried too hard..
[Nook Color Android Development] TheAmazingDave:
Yea, I tried it and didn't have any trouble connecting. I'd much rather use USB, though, just for the peace of mind with a physical connection.

I have a couple of those Cruzers in different capacities. None of them work directly, their power requirement is too hight. I don't have a hub to try them with.
[Nook Color Android Development] bradputt:
actually none of my thumb drives work, but all of my micro sd card reader works.
[Nook Color Android Development] skwalas:
For those trying to get usb flash drives to mount, there have been many reports (including from me) of various unpowered usb hubs successfully "masking" the power requirement of the drive and allowing it to mount.

I have a Sony 2GB that required too much power as well, would never mount, but it mounts just fine using an unpowered IOGear 4-port hub from radio shack.
[Nook Color Android Development] allerretour38:
Just wanted to repeat the request that someone made earlier for anyone who gets skype working to a usable level (a relative term, I know) to please post their configuration, primarily which headphones you're using.

I'm using this sound card with normal analog audio jack headphones, and the quality is not usable for skype (or at least I couldn't get it to work). The mic is functioning at some level, but voice comes out very broken up and distorted.

I have a PNY Atache 2GB that mounts and works perfectly.. though, it is an older model:

[Nook Color Android Development] :
I have a crucial drive that works perfectly without a hub . . .

http://www.amazon.com/Crucial-Techn...EM7E/ref=sr_1_1?ie=UTF8&qid=1311182480&sr=8-1

BTW. . . I also am wondering what the status might be on webcam support . . . anybody working on it?
[Nook Color Android Development] TheAmazingDave:
I have a few very generic thumbsticks that work, as well as a 1 gig HP v100w which performs flawlessly so far.
[Nook Color Android Development] viper2035:
Hi i can't get USB-Host working. I use CM7 136 nightly with OC Kernel from dalingrin. dmesg says something like:

rejected 1 configuration due to insufficient available bus power

92mA power budget left

is it right, that this means my usb device needs to much power and it doesn't work because of this reason? I try many different devices like Logitech MX518 and Logitech G11 also old little Laptop mouse and san disk 16 gb stick. None of them work. Can anybody help me?
[Nook Color Android Development] Divine_Madcat:
You are totally correct. To use those devices, you will need a powered hub (though, in some cases, an unpowered hub can mask the power requirement and still work).
[Nook Color Android Development] skwalas:
Yes. Your dmesg result indicates that the device has a power specification greater than 100mA , which is the maximum the nook can provide.

From my online research, a lot of devices will specify a "required minimum" power even though it uses less. Turns out many newer (read "USB 2.0") USB flash drives tend to specify 200mA or even higher (always in 100mA increments), since they can draw as much as 100-150mA during write operations. Older drives that mostly reverted more to the original USB 1.1 standard (even if they were labeled as USB 2.0 compliant) only drew about 50mA during the same write operations.

Try an unpowered hub and see if it masks or hides the power requirement. Alternatively, go for a powered hub.
[Nook Color Android Development] viper2035:
Thanks for answers. I already tried a unpowered hub...doesn't change anything for me...i will try to get a powered hub.
[Nook Color Android Development] Arbelzapf:
Does anyone have that webcam build? The link in the OP is down and I'd like to try it.
[Nook Color Android Development] nrune:
Can someone recommend a powered usb hub for nook color? I would love one battery powered.

Thanks!
[Nook Color Android Development] skwalas:
I've been searching high and low. Battery powered hubs just don't seem to exist.
[Nook Color Android Development] Moshe5368:
I am also in need of the camera app. Yahoo messenger does not see my camera and I have no idea how to set it up through android
[Nook Color Android Development] chisleu:
battery powered hubs are easy to make though. Use a USB Y cable and a USB power supply. You can get the power supply from radio shack or online (much cheaper online.)

They are just a battery with an integrated charger and a USB port and prongs for a wall jack.

Alternatively, you can get a solar USB battery which generate 120ma in sunlight and has a battery onboard so it can store up some sunlight and spit it out when needed.
[Nook Color Android Development] skwalas:
have actually been considering it. planning to make solar-recharged LED "lamps" for the deck, this would be similar. don't know enough about electronics yet, but that's what the arduino starter kit is for, right?
[Nook Color Android Development] bradputt:
Hi i have been thinking of making my own USB Y cable with a 5V power adaptor

searched the net but the only schematic i found is this, is it the correct way to connect it?
[Nook Color Android Development] miketunes:
Any tips for mounting USB storage devices?

I'm using phiremod v7 test 2 (based on nightly 136), with dalingin-OC-emmc-063011 kernal. I'm assuming all I should need to do is enable USB host mode in nook tweaks, than browse to /mnt/usbdisk?

I've tried a cruzer micro USB keychain, SD card/reader, and Seagate USB harddrive (externally powered with y usb cable). I don't see any notifications on the nook - the devices do light up so they are getting power though. /mnt/usbdisk always says empty, everything is formatted fat I believe.
[Nook Color Android Development] sisterchick:
Me too! I'm not having much luck mounting USB flash drive either. What am I doing wrong?
[Nook Color Android Development] newellj79:
Trying using a powered hub, unpowered. Worked for me.
[Nook Color Android Development] miketunes:
Hub isn't working for me. Should there be indication when the drive is plugged in (notification bar). Or we should just be checking /mnt/usbdrive? Does it make a difference using the nook power cable (extended tip) or a regular micro usb cable when plugging into the nook?
[Nook Color Android Development] lospulpo:
Not sure, It works fine for me whether it's the Nook's cable or just a regular micro USB. Yes, a popup should appear on the notification bar if you've got USB Host mode enabled (from Nook Tweaks). It'll let you know that a USB "SD Card" was detected and is currently mounted. Then you can browse to /usbdisk/ or /mnt/usbdisk/ and see the files. The notification will persist so that you can click it to unmount (safely remove)

I was having some of the same issues you described but when I updated to n136 or n138 It fixed itself.
[Nook Color Android Development] Moshe5368:
I have tried every combination of cables I can think of, have tried flash drive connected directly to the micro adapter, through a powered hub, through an unpowered hub, tried sd cards through a card reader and still cannot get the nook to recognize the cards. Running 7.1rc1 nightly 140. Do I need to set a mount point through ADB or am I just missing something?
[Nook Color Android Development] Moshe5368:
I should mention that I can connect a keyboard or a usb wireless mouse using the usb settings in nook tweeks but cannot mount any disks, either sd or flash drives.
[Nook Color Android Development] :
FWIW...

I can use basic (cheapo dell) mouse and keyboard with no hub.

A free flash drive (mass produced marketing one) I can use as well, with no hub.

My logitech keyboard, mouse, and cruzer mini flash drive I cannot use without a unpowered (not plugged into the wall) hub. From what I understand, the hub can "mask" the power requirements of the device in question. Not sure if that's good or not (don't think it's a big deal), but yeah...

If you turn on hosting, plug in the device, and open up terminal and type "dmesg" you will more likely than not see that you do not have enough power if you cannot use the device.

You really need a hub for things to be worthwhile. Maybe start following the cool backpack thread they have going on? Or just get one of those mini laptop hubs that can be powered (I'm sure they exist), and tape it on to the back of the NC.

EDIT: Just bought this: http://cgi.ebay.com/Real-USB-2-0-Hi...ultDomain_0&hash=item2eb68e3f87#ht_500wt_1200

Going to try it out and see if all hubs can hide the power requirements, or just the ones that can be powered. Anyone know?
[Nook Color Android Development] Moshe5368:
Perhaps you did not read my complete post. I have both a powered and an unpowered hub. A mouse, both usb wireless and usb and a usb keyboard are recognized and work well. My problem is that the nook does not even see the sd cards in the card reader or the usb flash drives. I have tried refreshing the devices and checking /mnt/usbdisk and /usbdisk. There is nothing there. My original question was if I needed to mount these devices manually through either ADB or through the terminal. I have looked at your backpack thread and while it is interesting, it is not really what I am looking for. I use a digital camera on the road and want to be able to download the media directly to the nook since I usually do not carry a laptop with me. Like several other photographers out there, I like to proof my pictures on a larger screen to ensure I have what I want from the shot. I used to use a laptop for previews but some areas I go make that less than practical. Try toting a camera and a laptop while repelling down a cliff. But I digress, thanks for your input. I will continue to search for a solution.
[Nook Color Android Development] newellj79:
I'm sure he read your entire post, I've seen him around these parts for awhile. I understand your frustration. I believe what he is getting at is not all hubs r created equal. Some work, some don't. Best bet is to get one that has been reported to work. This one works for me. http://www.amazon.com/gp/aw/d/B003V3DL86/ref=mp_s_a_9?qid=1311506899&sr=8-9. That is it works if I don't plug in the power adapter to it. I can use a keyboard, mouse, and mp3 player all at one with no problems. I hope my mic is at home waiting for me when I get back from vaca today. Will report on that to.
[Nook Color Android Development] :
Thanks for the vote of confidence newellj79 :D

Yes, I read your thread, but I usually try to add some extra info in there in case someone else is reading and thinks about a question that stems from yours.

Anywho, yes, I am thinking about your hub. If you want to try to troubleshoot it, plug the drive/whatever directly into the NC, then open up terminal and type "dmesg" (after you have host enabled and all). Try that, then get back to us.

EDIT: Ha! newellj79 has the same hub I do. Got it off ebay for $5 shipped:

[Nook Color Android Development] DigitalMD:
Moshe5368 :

If you can provide us your dmesg output, I'm sure we can help. Setup your hardware, open the terminal emulator , type "dmesg" you will see a lot of text. Near the end will be the pertinent lines regarding your flash drive.

Hit the menu button and choose Email to. This will copy the dmesg output into a email. Send it to yourself and paste it into a reply here and I will take a look.

Along with the advice about hubs and power, let me add that currently our device can only mount storage that is formatted Fat32.

Cheers
[Nook Color Android Development] skwalas:
Also, both lekofraggle and i have had success reading our camera cards (CF and SD) using the vivitar 50-in-1 card reader connected without a hub. I picked mine up at radio shack. If you want to take images off your camera card, this is perhaps a good way to go. As for hubs that mask the power draw on USB flash drives, I found the IOGear 4 port unpowered hub works for me (also from radio shack).

Just throwing it out there.

Also, that should be "rappelling" down a cliff...
[Nook Color Android Development] Moshe5368:
Thank you for the input, gentlemen. I have run dmesg with both of my hubs. The results are the same but dmesg reports that it identified all my devices. The report does, however, confirm your expectations that the power requirements are the issue. I found this to be odd even with a powered 7 port hub. The nook can identify the flash drives yet shows 92mv available and reports insufficient power available to mount the device.
[Nook Color Android Development] Moshe5368:
Thanks again for all the help here. I have identified the issue which was, as expected, insufficient power to mount the drives. I did, however, find one of my flash drives which would mount. It is a PNY micro flash drive 4 GB which is identified and mounted correctly. I'm off on a quest for a functional hub (I hate to mail order anything). There are several electronic supply options within a 30 mile radius of me so I should be able to locate a hub which will function correctly. If I can find a hub which will power my card reader, my issues will be solved.

Once again, thanks for all the input and assistance in tracking the problem. These forums are the real reason open source software will always be superior to it's alternitives. Now I'm back to work. This fall is my trip to Grand Canyon for another photo shoot down the canyon trails. Now I will be able to check out my shots with a great deal less baggage.

Just got a USB sound adapter and a 3.5mm mic for it. It doesn't work at all. Were there some sort of extra files that needed to be added? I mean I get nothing.
[Nook Color Android Development] DigitalMD:
More details needed. What build version are you running?
[Nook Color Android Development] lospulpo:
This might sound dumb. I'm trying to charge the Nook the same time as I use USB Host.

Can I just plug a usb charger into one of the ports on my 4-way unpowered hub? With External VBUS installed of course.

Or is there a better proper way to do this now?
[Nook Color Android Development] viper2035:
I try a usb sound card that comes with a panasonic headset. The output does work excellent but I have no Headset with 3.5mm at the moment to try the input. Does output work with your card?
[Nook Color Android Development] newellj79:
Nope, I get nothing thru the headphone Jack of the adapter either. I'm using n143 by the way.

Has anyone had any luck getting a webcam to work through a powered hub? Would like to get yahoo messenger video or tango working if possible. I have been able to get all my flash drives to work through an unpowered hub. Sandisk, PNY, sandisk cruizer. It reads them all with no issues. Still cannot get my card reader working. It draws too much power. The webcam is the same. Dmesg recognizes it but cannot power it.
