ADVICE/SUPPORT : UVC Camera on Samsung Galaxy Tab 10.1- No device Node??

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.
Rgds,

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.

[Solved] Take screenshots of the first launch of ROMs

Hello
I do not think my question is specific to the Nexus tablet 7, but I post here
I want to make presentations of all rom available for Nexuz 7
but from the beginning to the end
capturing the screen at each step: from creation of the google account or the connection to existing google account until utilization the ROM
Only, usb debugging is not enabled by default
I do not know how.
I thought:
1 - Install the ROM
2 - enable usb debug
3 - delete a file that will allow, when restarting the device, starting settings from the beginning to the end while having the ability to take screenshots.
I am currently:
Root
I installed CyanogenMod Version 10 cm-10-20121129-NIGHTLY-group
My recovery is 2.3.1.1 TWRP
My computer is equipped with:
Kubuntu 11.10
Android SDK installed and operational and QtADB

I'm now on kubuntu 12.10

is it possible to make screen capture of the first launch of a ROM?

Solved, i have flashed multirom

[Q] Dual boot Windows and Android possible on LENOVO YOGA 2 TABLET 1051?

I have Lenovo Yoga 2 Tablet 10" with windows 8.1 (1051L)
its hard to use windows 8.1 on a tablet.
can i install Android on my tablet or even better ... dual boot with windows and android possible on this tablet?

it' fantastic. I have yoga 2 10 with android 1050L. It's very speed. but i think the problem is bootloader mods.

I think I would rath:cyclops:er run Android as the primary OS and the run Windows as a VM.

How do you do that ? I need WM for a private app.

Successfully booted Android 4.4 R3 X86 from USB...
Hey all,
I have successfully managed to boot the 4.4 R3 efi img file from Android X86 on my 1051F. It's working pretty well, very smooth, but pretty much none of the hardware works (GPS, WIFI, Bluetooth, rotation, sound, etc).
Anyone have any idea how we could fix that? The process for getting it to boot is actually pretty easy. You download the img file from the android x86 site, use Rufus to create a bootable USB key (being sure to set it to GPT for EFI). You then need to disable secure boot on the tablet (instructions found various places on the net if you don't know how), shutdown the tablet, connect the USB key via OTG cable to the tablet, hold the volume up and power on. You will get into the NOVO menu. Once there, select boot menu and boot from the USB key (if it's not listed you probably didn't create the USB key in GPT, or it was detected when you powered on).
In order for it to boot into Android, you'll need a USB keyboard connected to select the android option. Alternately, you can just modify grub.cfg to set a default option and a timeout (which is what I did).
I'd really love it if anyone can provide some input on how to fix the missing drivers. Since the 1050 tablet is basically the identical hardware, I would think it should be easy to get the drivers over to this image, but I just don't know how.
Any help greatly appreciated!

I know it sounds basic, but have you tried getting the drivers from here: http://support.lenovo.com/us/en/products/tablets/yoga-series/yoga-tablet-2-1051
I wanted to do a fresh install of Windows 10 and I got the drivers from this place.

Thanks for the suggestion, but I'm pretty sure they only provide Windows drivers there. From my experience, Android drivers tend to need to be part of the image you install from, though I'm sure more advanced users could probably add drivers to a live install.
I'll take a look anyway, just to make sure, though.
EDIT: Just checked and, as I thought, only Windows 8 and 10 drivers. Realistically Lenovo don't support running Android on the 1051F, so it's pretty unlikely that they'd ever post drivers like that, unfortunately.

My apologies. I misread the post. I thought you were looking for the windows drivers. I am sorry to have given you unnecessary hope!

What's this got to do with the Tab S?

wanted modified grub.cfg, please share

UPDATE: Today I tried and succeeded to get Android 5.1.1 running in the same way. I got the image from the android-x86.net page and it runs very smoothly with working WIFI. Just need to get the rest of the drivers working and add all the google apps (they aren't included in the image).

Hi,
I installed x86 android 6.0 Rc2 on my 1051F too, but I got freeze sometimes Wifi is working....but Screen Rotation Not. Any ideas?
Greetings

Could you go farther in detail about when it freezes and if it is going into sleep mode and back out?

You'd need to add support to kernel if you want to use the dongle on your phone over OTG.
There is a experimental entry in Kconfig for Realtek devices which have not been tested, enabling that might work. Else you will have to add support yourself.
Either way you'll need to compile your own kernel for it.
Have you tested by simply inserting OTG and dongle and see what happens?
Since phone has wifi already (I guess) it might not work if internal is interfering with external.

I had to add that driver to several linux kernels that i use on my machines (Ubuntu and OpenElec).
Never tested on my Mate 10 Pro, or any other Android device.
However, adding that to the kernel would require some work and i'm not even sure it works fine on android.
Here's a link to my github - > https://github.com/pretoriano80/RTL8822BU

thank alot for your help..
...Oh, I forgot to say that My device The model name really is named Realtek 8811CU Wireless Lan 802.11ac USB NIC.
I use the 8811CU driver installed on linux. It can connect and use normally. But the driver that came with the device The name is back. This model is RTL88x2BU. Will it work as well with the links you recommend?

There is no easy way to do that. First you will have to check if your kernel has support for that Realtek driver and it it does, enable it (as ante0 said).
If it doesn't have support for that driver, then first compile the kernel from sources (without any modification to the source) and check if your device will boot, if it doesn't, then you can stop here and forget about adding that driver to the kernel.
If it does boot with the compiled kernel, then you will have to add the driver to the source code and here, again, there's no guarantee it will work. (compilation might fail or simply, the kernel builds just fine but the driver won't work... like i said, there's no easy way for this).
In my opinion, you better start searching on GitHub for an android kernel that already has support for that driver, but you will also have to check the kernel version (if it matches yours, then you have higher chances to port it for your device's kernel).
Best option : Buy a Wi-Fi adapter that have in-kernel support already.
