HI,
I am trying to interface the UVC Camera to the Samsung Galaxy Tab 10.1(GT-7510) , but I am not able to see the device node getting created in the shell( I have installed the Linux terminal Shell Application) and rooted the device using this Video .Can somebody plz tell/advice how I can achieve it and access the device Node or at-least get it created.
Following is the log on dmesg :
usb 1-1 new high speed USB device using tegra-ehci and address 97
hub 1-0:1.0 unable to enumerate USB device on port 1 ,
usb 1-1:device v0ac8 p3420 is not supported
On My Laptop I get this output on Dmesg :
[12307.364237] uvcvideo: Found UVC 1.00 device Venus USB2.0 Camera (0ac8:3420)
[12307.366108] input: Venus USB2.0 Camera as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1/2-1.1:1.0/input/input14
[12308.537059] usbcore: registered new interface driver snd-usb-audio
also i can see the camera getting blinked on connection which proves that it is getting the power-supply and getting connected with the system.
I think there is a support for UVC USB devices in the kernel (not sure) otherwise I am ready with the Kernel For Samsung Tab 10.1 (GT-7500 (Higher Version: GT-7510)) from here .(GT-P7500_MEA_Opensource.zip (requires Login).
Plz assist.

You seem to know a bit about what you're doing. I'm not really familiar with this device. I did a search and did not find anyone who has don't this yet. The first priority is to get a Linux device in /dev/ folder. This is generally handled by a device driver and a udev rule. Try the newer kernel if you can. The android 4.0 ics has a Linux 3.x kernel. See if switching to ics helps. Try compiling a custom kernel with all modules. Once you have a device, try using SSH or sftp from your desktop under Linux to stream from that device with vlc or another media player.
Do you have any examples of this device in use on mobile Linux? It may require writing an entire kernel driver.
HI,
Yes that is the same line of thinking for us as well.We are trying to compile the kernel and load it .- Ongoing
I believe only the zImage is the one which is to be flashed.But I am little scared to do this.Couldn't find the instructions to loading the Zimage even though I can compile one.

Flash it with Heimdall, even if it won't work you will be still able to get into download mode of bootloader (which you aren't supposed to flash) and reflash the kernel with stock one.
Hello,
I'm very intrested about enabling OTG on my Nexus 4 in order to plug it to my DSLR camera,so I can use apps like DSLR Controller with the Nexus and the camera.
I came across ziddey's thread (1) and CaptainMuon's thread (2)
So I bought myself some cables and now I have some questions before I begin:
1) Because I'm using a camera,a device that doesn't need any power from my Nexus,do I still need to supply any external power to the USBs?
2) In ziddey's thread he mentions that if you have a digital camera (or other devices that won't require power),you should manually enable OTG
on your device
OTG state can be manually set to host, none, or peripheral (shouldn't ever be a reason to need to set this one) via /sys/kernel/debug/msm_otg/mode. Execute the following as root (adb shell over wireless, terminal emulator, etc):
Code:
# echo host > /sys/kernel/debug/msm_otg/mode
or
# echo none > /sys/kernel/debug/msm_otg/mode
Click to expand...
Click to collapse
So my question is, do I still need the custom kernel etc to enable OTG on my device or should I just enter these commands and im all good?
Sorry if my questions are dumb,as you can probably already tell,im new to this.
Thank you!
Bump... Please help if you can
So I installed backtrack 5 successfully on my Note II running ARHD 14 and Perseus kernel, but I have a little problem. I can partially run airmon-ng but the internal wifi adapter can not be used in monitor mode so I want to find out how I can make a WN722n adapter to work using OTG adapter.
Backtrack seems to recognise the adapter as shown by the lsusb command. So I think is driver related the missing part to make it work. Any idea where I can find and how I can install the appropriate driver to work?
Anyone have an idea?
Hi,
can you please send me the post or the HOWTO you used to install BT5 on note 2 ?

All linux OSs that has been ported to android, are not quite perfect. They are still in beta. So some things may not work. If I will find solution how to fix that. I'll post it here as soon as possible.

while i can not help you out, i would just like to say that having bt5 running on that bad boy just sound awesome.
are we talking command line or GUI ?
i would love to see a video if you find the time.
While i have no idea where to ask, i don't think this is the right place. i am not sure it will be helpful in any way but there was a lot of work put into porting BT for the original Xoom, and as i remember, it was also using an adapter to set monitor mode. you could maybe ask it as a general question and not device specific, and get some useful information that way. i will look into it when i finally get my Note II.

Hello, nookies!
Today I have decided to make an easy-to-follow guide on mounting USB devices (cameras, USB sticks) on your Nooks! Hooray! :good:
DISCLAIMER - I am not responsible if you brick your Nook, break your USB device, the current state of the economy, or why Obama is the president. Please do research on these topics if you would like to know more.
DISCLAIMER 2 - I did not make either of the apps attached, I have merely posted them here for easy access.
So let's get started with some prerequisites!
Prerequisites:
A rooted Nook Touch or Nook Touch Glow with software 1.2.1 installed, as well as Superuser and su binary installed
A terminal app (attached below)
Renate NST's UsbMode.apk (attached below)
A USB host-enabled kernel correctly installed and working (see my signature for a Nook Touch Glow one)
A USB OTG cable
Steps:
Make sure that your Nook is completely charged before continuing!
Make sure that your kernel is definitely working and that USB mode is properly working, too!
1. Open up Renate NST's UsbMode.apk app. Tap the "Off" button. (This will stop your Nook from trying to charge itself from the USB device by turning off the current.)
2. Plug your USB OTG cable (without anything attached to it) into your Nook's USB port.
3. Tap "Host" in the UsbMode app. (This turns on Host mode.)
If the LED beside your Nook's USB port has turned solid green at this point, you are doing well!
4a. For USB devices that have a separate cord (cameras): Turn on the USB device. Plug its cord into its USB port. Now, connect both the device's cord and the device into the open end of the OTG cable that is attached to your Nook.
4b. For USB sticks/drives: Plug the drive directly into the open end of the OTG cable that is attached to your Nook.
5. Tap "View USB" in the UsbMode app. You should see the Nook's main listing at the top, as well as the plugged-in device's listing under it. The device's listing should have a black dot next to it.
Good job! You're doing well so far! :laugh:
6. Now, open up the Terminal Emulator app I attached below. You should have installed it already. When it opens, you should see a dollar sign ($) at the far left of each line.
7. Type in
Code:
su
. Now, instead of a $, there should be a # at the far left of each line.
8. Type in
Code:
mount -o rw,remount rootfs /
. This remounts /system as read-writable.
9. Type in
Code:
mkdir /usb
. This creates a directory called /usb in the root of your Nook's filesystem; it will be used to mount your USB device in.
10a. For USB devices (cameras, etc.), first type in
Code:
mount -t vfat /dev/block/uba /usb
. You will get some sort of error message, that's okay. Now, after typing that, type in
Code:
mount -t fvat /dev/block/uba1 /usb
.
10b. For USB sticks/drives. just type in
Code:
mount -t vfat /dev/block/uba1 /usb
.
11. If the above commands worked properly, you should now be able to go into a file explorer, navigate to the /usb directory, and boom! You can now manage your USB device's filesystem straight from your Nook!
Unmounting your USB drive
It is important that you unmount your USB device/drive properly before physically taking it out of your Nook. Here's how to do that.
1. Open up your Terminal Emulator app again.
2. Type
Code:
su
.
3. Type
Code:
mount -o rw,remount rootfs /
.
4. Type
Code:
umount /usb
.
5. Type
Code:
rmdir /usb
.
6. Take the whole cord/USB drive out of your Nook with the OTG cable.
7. Open up the UsbMode app again.
8. Tap "Auto". (This turns your Nook's current back to being automatically determined, instead of being off.)
9. Tap "Peripheral". (This makes your Nook return to having the ability to charge from an AC outlet (or whatever).)
10. You have successfully unmounted your device!
Hope this helps all of you guys who want to manage your USB devices on your Nooks! :good:

I hate to do this, but...
Bump.
I'm sure that someone can profit from this tutorial, right?
There was a whole thread on using my modified volume daemon to do this all automatically.
I've pretty much abandoned that train of thought.
I'm not really sure that anyone really wants to mount USB drives.
It's really a pretty current-intensive way to get data.
It's better to just use a 32 GB SD card in the Nook, formatted with something better than vfat.

thanks for the efforts @Renate NST in creating the USB mode app, I really envy you guys for the knowledge and understanding you have of the tech involved.
I agree with you on the practicality of the application.
At the same time and more we can never let go off the THRILL in trying the invaluable efforts you manage to put in.
Kudos.
Coming back to the thrill of it all ...
@NoogiE ... thanks for the link to this thread ...
i am on 1.3.4 version of your 1337 ROM, assuming the USB kernel is in place, i opened @Renate NST's USBMode app and pressed Off, then i connected the OTG cable and pressed Host ... no action no led action ... if you can help ... thanks.
thanks,

Hmm. You have this rooted and the UsbMode is not showing any "<errors>"?
You're sure that it's an OTG cable? (I've never seen one over 6" long. If you know of a longer molded cable, please tell me!)
You're sure that your kernel has the OTG fix?
You should get a quick flash (50 mS or so) out of the LED just pushing the host button on UsbMode even with nothing connected at all (no adapter).
With an adapter connected you should get a solid LED.
I've never gotten into writing/patching kernel drivers, but I always thought that someone would fix the buggy USB driver so that UsbMode would not be needed for regular OTG operation.

Hey thanks for looking into it @Renate NST ...
I am using the small 4-5 inch cable ... had a spare lying around.
I am not getting the quick flash you talk about while a press the Host button.
However when i open the USB Mode app the first line 'Request' shows empty, when i press the Host button it says <write error>
when i engage the buttons (off, 100mA, 500mA, 1.5A & Auto) the Max Current line blinks between <write error> and Auto ...
If that helps !!!
and the kernel part, I am running a copy of Yattaro and Nookie's 1337 ROM(the latest 1.3.4) which claims it supports USB host capability.
Is there any way i can run a command to check if the kernel supports ? Not that i doubt/question this ROM developers efforts/claims.

You seem to be having a an su binary issue. Check and see if the su binaries are in /system/bin; if they aren't, copy them there from /system/xbin and reboot. Should work like a charm.

hey Nookie ... copied the su to to /system/bin and the led came up ... but i can't see the connected device under 'View USB', could it be bcos i am using a Micro SD card on in USB adapter ?
PS: and hey i saw swapon and swapoff files(binaries?) in /system/xbin, does it mean your ROM supports SWAP ? With swap and hopefully NookKat the RAM deficit could be manageable ? My first Android Device was LG Optimus Pro, C660 which had 256 MB RAM & 140-160 MB internal storage for apps, The stock ROM used to keep popping the close any programs popups every now and then rather freqeuntly, On a custom CM7 official port ROM with swap support & dark tremors ap2sd scripts, i was able to get rid of the annoying pop up and install 60-70 user apps to SD card and still have a daily ROM. Do you think our device supports a similar setup with swap and darktremors aap2sd scripts ?
thanks
Quick N00b question- I am trying to get a GPS signal into my rooted NST. It has a micro USB. Do I need to do this in order for an app to get my serial signals?
I will paypal someone to help me get GPS signals into my NST using an app called Simple Sailor! Thx

Is an app that can see what serial data is being provided via USB? Or, a GPS testing app that grabs data from the USB. Do apps always look for GPS data to come in via USB or is there another place that an app would look for GPS data?

To tell you the truth, I don't think either of those exist. I could be wrong, though - @Renate NST has done some stuff using an old GPS puck on her Nook, so you can ask her.

Hey thanks Nookie. I have found some info from both Top hat Soaring (glider people who needs daytime screen visibility as well as ADV riders - motorcycle navigation with again, daytime visibility) so I'll be pursuing those. Thanks again.
I looked into all this a while ago.
You should be able to go right from serial into the LocationProvider.
Strangely enough, most of the stuff I saw back then was using the mock location to handle the data.
This seemed like a detour to me.
I really should follow this up.
Using USB host mode and serial USB is not optimum due to the wackiness in the USB driver and the current draw.
This is a 1.8V GPS module: https://www.sparkfun.com/products/10890
Besides the advantage of low voltage/low power, the 1.8V serial can interface internally and directly to the Nook.
I think that I'll be ordering one of these.
I do not know anything about programming.
But I can do all the manual. ))
What am i doing wrong?

It looks like your Nook is not recognizing any drives being plugged into it.
Can you give me some more details on your progress thus far?

Hello,
I need a ROM with built-in OTG because my Nexus's screen is dead and I want to use a mouse with my powered usb otg hub to install debian and set a little home server.
I tried Chroma and Nitrogen without success.
Thank you!
That feature is mainly kernel related. So you gonna find a kernel with usb otg
I tried pure nexus with hellspawn N4 which has built in otg but no otg out of the box, I can't use the touch so I can't try app or settings :/
Also I have a bluetooth mouse if it easier to set it via adb but I don't know how..
Not sure how to set it via adb in hellspawn, but in Quanta, it can be set by issuing the following command...
Code:
echo "1" > /sys/module/msm_otg/parameters/otg_hack_enable
Can you tell me a good rom with ? Because pure nexus is 6.0.1 and Quanta is for 5.1 :/
PS: I tried the command but nothing
Ok so thanks to this usefull programm http://marian.schedenig.name/2014/07/03/remote-control-your-android-phone-through-adb/ I can pair my bluetooth mouse and use my phone !
Actually it is pretty simple it takes screenshot of the phone and use adb click to send touch input.
Quanta is also for marshmallow
