[Nook Touch General] desitdt:
my powered hub does not have a big diode.

Also i was reading from here, wht doeds it seem so simple according to this page?
[Nook Touch General] Renate:
Did you check to see if it powers Vbus on the host side when plugged in?

If you can do it, a photo of the inside of the hub would be useful.
[Nook Touch General] desitdt:
Would i need to connect a wire at the red line in the picture below?
[Nook Touch General] Renate:
How did you manage to get the camera glare exactly on the point of interest? :p

I think right above the "B" in your "USB POWER" annotation is an RF choke and above the "O" is a pass transistor.

Yes, you can try with the red wire, but it would be a bit better to connect it to the other side of LB1.

Check it with a voltmeter to make sure it's not a lot more than 5V after you are done.

5.010 V or so is fine.

Be careful.
[Nook Touch General] desitdt:
how about this one? and you mean loop it around the board?
[Nook Touch General] Renate:
No, I just mean in that photo connect everything on this face of the board.

The wire that goes to LB1 should be on the contact near the edge of the board.

The other end of the wire can go to the center pin of the power connector where you had it.
[Nook Touch General] desitdt:
Which component is this circuit is preventing the power from going to the usb. I assumed it would need a diode that i would be jumping.
[Nook Touch General] Renate:
The transistor is being a low drop diode.

You are basically bypassing it.

May be the usb OTG cable.

I'm getting a similar issue, it may be the usb OTG cable that won't let me charge. I didn't read thoroughly on the one I grabbed, and it doesn't specify "charging", and it doesn't appear to charge. The best I can get is "Not Charging". I don't see why it would make a difference though. It puts 5v on the same wire that should accept the 5v. I verified 5v on the OTG micro-b end with a my multimeter attached to a sewing needle, and It powers the keyboard fine. I even tried cutting a usb cable and putting 5v directly in the 5v line. Same result.

This is what I got.

dx.com/p/micro-5pin-to-usb-female-otg-data-cable-black-129671

I may try to get one that has been known to work.
[Nook Touch General] Renate:
"Not charging" is when it has voltage but doesn't feel like taking it.

Try hitting the button for 1.5A
[Nook Touch General] stephen.george.west:
Nothing wrong with the +5v on the line is what my burned fingers tell me (500mA sure heats up that 100Ω resistor fast). None of the buttons do anything other than kick it back to "Discharging".

It does happily charge in host mode auto using a regular cable going back to the slave side of the same hub on the same power source.
[Nook Touch General] Renate:
It sounds like your wall wart doesn't have sufficient power.

Check the voltage under load.

Can't reliably read USB host while power is connected

Renate NST, thanks for your work on the Nook Touch Simple in this thread and in the USB Host Nook developer thread, http://xdaforums.com/showthread.php?t=1457971. I've been able to connect up a GPS USB feed into my Nook.

I am also able to supply 5v to power the nook while it is connected to the external GPS feed.

However, I am having a problem with the /dev/ttyUSB0 port stopping and not being able to restart it.

My cabling is as follows:

I have a GPS Hockey puck plugged into the OTG cable. I also have a 5V DC power source spliced into the red and black USB leads.

It works correctly immediately after I boot the NOOK. I run the following "initusb.sh" script that allows me to

read and write to /dev/ttyUSB0

echo 500000 > /sys/devices/platform/bq24073/regulator/regulator.5/device/force_current

echo host > /sys/devices/platform/musb_hdrc/mode

sleep 0.5

echo host > /sys/devices/platform/musb_hdrc/mode

sleep 0.5

chmod 666 /dev/ttyUSB0

However, if I subsequently run my "deinitusb.sh" script, then I cannot re-initialize the USB unless I remove the 5V power:

echo peripheral > /sys/devices/platform/musb_hdrc/mode

sleep 0.5

echo peripheral > /sys/devices/platform/musb_hdrc/mode

sleep 0.5

chmod 500 /dev/ttyUSB0

echo 1500000 > /sys/devices/platform/bq24073/regulator/regulator.5/device/force_current

But, if I remove the 5V from the red usb pin, then I can successfully rerun the initusb.sh script and it will correctly allow read/write

to ttyUSB0 again.

The problem I have is that sometimes (for an unknown reason) the state of the USB host fails (usually several hours after running initusb.sh),

so I can no longer read or write to /dev/ttyUSB0. In this state, I cannot figure out how to programatically restart the ttyUSB0 port.

I try running deinitusb.sh followed by initusb.sh, but it does not work. Unless I remove the 5V power, in which case I can reinitialize the

ttyUSB0 port using the scripts.

The goal is a reliable USB app that runs on an external battery. Do you have any suggestions how I might either issue different

commands via a script, or run java commands or run diagnostics to figure out how to fix this problem with /dev/ttyUSB0 ?

Thanks,

Rob
[Nook Touch General] rdunning0823:
Can't reliably read USB host while power is connected (cont)

More information about the problem:

I found this info about OTG specs (in wikipedia) (new members can't post links to this forum)

Three additional ID pin states are defined[6] at the nominal resistance values of 124 kO, 68 kO, and 36.5 kO. These permit the device to work with a USB Accessory Charger Adapter which allows the OTG device to be attached to both a charger and another device simultaneously.[8] These three states are used in the cases of:

A charger and either no device or an A-device that is not asserting VBUS (not providing power) are attached. The OTG device is allowed to charge and initiate SRP but not connect.[8]

A charger and an A-device that is asserting VBUS (is providing power) are attached. The OTG device is allowed to charge and connect but not initiate SRP.[8]

A charger and a B-device are attached. The OTG device is allowed to charge and enter host mode.

I think what I want is the last state: the "B" device is my GPS Hockey puck, and I want the host to enter charge mode.

Interesting, I found another post from guys who I guess work on kernels, that the tw4030 usb chip (that used in the Nook I believe) does not detect the above resistances on the ID pin: (sorry as a new member to this forum, I can't post external links, but this conversation says,

However that appears to be selected if the ID resistance is 36.5Kohms, while

others are selected for 68Kohm and 124Kohm.

But the twl4030 cannot detect that distinction. The cut-offs are

Ground, 102K, 200K, 440K, Floating​

So, I think my next steps will be to break apart some OTG cables and try putting the three resistances above into the GND/ID Pin short (pins 4 and 5) and see if this allows my software scripts to reliably enable/disable the USB host while the 5V is connected.
[Nook Touch General] rdunning0823:
Here are the results of trying different resistances on the PIN4/5 of the USB cable.

Test configuration:

* 5v on VCC

* TrendNet TU-S9 serial usb converter hooked to OTG cable, providing stream of GPS NMEA data. Note the resistances were

measured using a medium quality multi-meter, so they may be off by a few percent.

* kernel is uImage_mt_usbhost_115.zip

Summarily, none of the resistances either published in the OTG spec or those reportedly recognized by the tw4030 chip

fixed the reliability issue of being able to restart the ttyUSB0 while 5V was connected to VCC.

Resistance: Results:

0O (grounded - standard OTG cable)

power up and run initusb.sh. GPS data is present on ttyUSB0

run deinitusb.sh. GPS data stops on ttyUSB0

run initusb.sh: GPS data does not reappear on ttyUSB0

23.5kO

power up and run initusb.sh. No ttyUSB0 exist

97kO

power up and run initusb.sh. GPS data is present on ttyUSB0

run deinitusb.sh. GPS data stops on ttyUSB0

run initusb.sh: GPS data remains missing on ttyUSB0

eventually ttyUSB0 disappeared and ttyUSB1 appeared (after repeatedly

running initusb.sh and deinitusb.sh)

123.5kO

power up and run initusb.sh. No ttyUSB0 exist

147kO

power up and run initusb.sh. No ttyUSB0 exist

196kO

power up and run initusb.sh. No ttyUSB0 exist

219kO

power up and run initusb.sh. No ttyUSB0 exist

437kO

The TPS65921B does not have a full USB ID ADC.

See http://www.ti.com/lit/ug/swcu067c/swcu067c.pdf page 44.

You could also look at the source code for the driver.

It has two detectors, for shorted and floating.

[Verizon Samsung Galaxy S III] coldcaption:
On my old Droid X, custom roms left the option there to set your own thresholds to ambient light as well as custom brightness levels. This was necessary, due to its weird reporting of ambient light to begin with.

On CM9 on the X, that would be under Display in the system settings. With CM10 on the S III, there's no such option. On Samsung's stock rom as well as on CM I find that auto brightness sets the screen too dim. Can those levels be adjusted? Thanks!

when you say base, what do you mean? i'm using the latest stock OTA from the shooter
[EVO 4G Q&A, Help & Troubleshooting] -EViL-KoNCEPTz-:
When you port a rom you have 2 roms you're working with a base and the one you're porting, to make it simple its best to use 2 roms that have the same screen resolution and same processor type. The evo is a single core processor , hdpi resolution and the 3d is a dual core processor xhdpi or qhd resolution. When working with these 2 to make a port any graphics and ui elements from the shooter need to be resized to fit the supersonic screen properly, and changes need to be made in alot of the system files for the rom to use the processor right. For someone with little to no experience doing a port and due to time it would be easier and quicker to find a stockish shooter rom already ported to the evo and remove root, otherwise you will be spending weeks resizing graphics and learning what need to be modded for the processor to work right. Most 3d ports take around 2 wweeks to a month depending on the time per day modifying the graphics and system files mostly cuz there's is just so much go modify and its time consuming. However stripping root should take no more than a few hours depending on your knowledge level, I could probably remove root in about 10 minutes cuz I know what files to look for to delete and where to look for them. If you want to learn to port roms id suggest starting with 2 roms with the same resolution and chipset for your first few tries and then expanding from there as your comfort level improves and you are successfully making booting ports the flash with no errors.

For a beginner I suggest starting with just a few tools like dsixda kitchen, tommytomoatoes android utility and gimp for editing graphics unless you already have Photoshop, gimp is free and does everything Photoshop will do you just have to download plugins and brushes to beef it up from the base install, deviant art has alot of brushes you can download and the gimp repository has alot of plugins you can pick and install

Edit: also learning to use Linux (Ubuntu, opensuse, mint which even you choose) will help if and when you decide to dive deeper and start working with source to compile roms and build from raw source, notepad++ is also a must for editing the source code in decompiled apks and updater binaries.

[Samsung Galaxy Nexus] dionieins:
So my question is pretty simple:

if I buy a Galaxy Nexus from someone on eBay (a Galaxy Nexus that

is not

for sprint or verizon) and the phone comes with ICS:

would I be able of updating it to the latest version of Jelly Bean, so the phone is just like the ones that the Play Store is selling right now?

PLEASE LET ME KNOW! AND SORRY IF THE QUESTION WAS TOO STUPID, BUT I JUST WANT TO BE SURE THAT I'LL HAVE A

STOCK-STABLE JELLY BEAN VERSION ON MY PHONE
[Samsung Galaxy Nexus] martonikaj:
Unless he said he bought it from the Play Store, just statistically the chances are it won't come with "takju" or "yakju" firmware on it (and considering it still has ICS, I'm about 99% sure it isn't takju/yakju). This means that the device isn't updated by Google, but rather Samsung. More broadly, that means that it won't get an OTA for a while, as the Samsung updated devices are slower on the OTA train than the Google ones.

Doesn't really matter though, as if you're willing to spend a few minutes figuring out how to run a command line, you can flash

any GSM Galaxy Nexus

to "takju" firmware, and be on 100% stock 4.1.1 Jelly Bean, and receive OTAs directly from Google from that point. If you do so, I highly recommend you follow this post, which will give you an idiot-proof guide to flashing to stock takju: http://xdaforums.com/showthread.php?t=1626895

Basically though, think about how much you're paying for that eBay phone and consider just buying one from the Play Store for $349. It's a fantastic deal and you'll get a brand new phone with a complete manufacturer's warranty. Something to think about.
[Samsung Galaxy Nexus] dionieins:
thank you some much, amazing help here!

Thanks a lot for your answer, you solve all my questions about the topic, I really appreciate it!

So I did as you told me because I found it was a good advice, so I bought the phone from the Google Play Store and actually it came with ICS, but as soon as I synced it with my google account immediately offered me upgrading to Jelly Bean, so now the phone has the 4.1.1 version.

The phone is fast just out of box so that's pretty good, but I was reading about Trinity kernel I'd like to hear your opinion about. To be more exactly, does it worth it to change the rom and kernel considering how fast already is? There is big improvements in battery without loosing too much stability?

Please let me know your opinion as I consider that you're really well informated

thanks in advance!
