Hello all, Some notes for persons, who would like to use AR1100 (USB mode) with UDOO under Android. At first useful links: 1. https://www.adafruit.com/product/1580 - AR1100 from Adafruit 2. http://a20androidincar.wordpress.com/co ... uchscreen/ - Configuring the resistive touchscreen ( example) 3. http://pccar.ru/showpost.php?p=283807&postcount=8 - Vendor_04d8_Product_0c03.idc OK, now the procedure: 1. Create file "Vendor_04d8_Product_0c03.idc" and put to the "/system/usr/idc/" (see link [3] for detailed information) 2. Change file "/kernel_imx/drivers/input/touchscreen/usbtouchscreen.c " 3. Rebuild and refresh firmware on sdcard PS: a modified "usbtouchscreen.c" must be fix for support all previous devices today modification correctly support only ar1100. only for test purpose. A modified usbtouchscreen.c Code: /****************************************************************************** * usbtouchscreen.c * !!!!! for test purpose only !!!!! * modified by Vladimir Khudoshin <cmex81@gmail.com> for AR1100 (HID-DIGITIZER). * needs to be corrected for support all previous devices and a new ar1100. * current modification correctly support only ar1100 * * Driver for USB Touchscreens, supporting those devices: * - eGalax Touchkit * includes eTurboTouch CT-410/510/700 * - 3M/Microtouch EX II series * - ITM * - PanJit TouchSet * - eTurboTouch * - Gunze AHL61 * - DMC TSC-10/25 * - IRTOUCHSYSTEMS/UNITOP * - IdealTEK URTC1000 * - General Touch * - GoTop Super_Q2/GogoPen/PenPower tablets * - JASTEC USB touch controller/DigiTech DTR-02U * - Zytronic capacitive touchscreen * - NEXIO/iNexio * * Copyright (C) 2004-2007 by Daniel Ritz <daniel.ritz@gmx.ch> * Copyright (C) by Todd E.

Please, use this link: https://a20androidincar.wordpress.com/c ... uchscreen/ for eGalax usb touchscreen, or I can modify source within next few days and upload to forum: support ar1100 and eGalax... but I will wait feedback, because I have only Ar1100 and can't verify for eGalax
Hi cmex81, i try it this procedure for egalax but is not working. i don't have any point touch. I try it also other procedures without success. On another forum i saw the same problem with egalax + android 4.3 , and the problem was fix it efter upgrade to android 4.4. unfortunately we have no OTA very soon, i think. Thanks.
Hi idorel77, could you post link for your touchscreen... I'll try to find in my city...(if touchscreen not expensive for purchase , I'll try to make a patch)
Hi , thanks a lot. The touchscreen i buy it from ebay http://www.ebay.com/itm/8inch-4-wire-Re ... 53fc838e7f USB TouchController: Product ID: 0x0001 Vendor ID: 0x0eef (D-WAV SCIENTIFIC CO., LTD.)

Location ID: 0x14100000 / 27 Current Available (mA): 500 Current Required (mA): 100 If u can't find , i can test every modification if this can help.
Hello cmex81 , today i recopiled and i used your metod with a modified usbtouchscreen.c too. But i have same result . Note: i use the touch on raspberry pi and its working.
Hello, I have the same issue with idorel77. I found https://github.com/UDOOboard/Kernel_Unico is the source code that udoo team published. The device that i have is again same with idorel77's screen. Product ID: 0x0001 Vendor ID: 0x0eef (D-WAV SCIENTIFIC CO., LTD.) Version: 1.00 Speed: Up to 1.5 Mb/sec Manufacturer: eGalax Inc. Location ID: 0x14100000 / 27 Current Available (mA): 500 Current Required (mA): 100The code that you shared has the code line; {USB_DEVICE(0x0eef, 0x0001), .driver_info = DEVTYPE_EGALAX}, Seems that if i recompile the source code, the device will work. (Also i have to do https://a20androidincar.wordpress.com/configuring-the-touchscreen/) But i really dont know how can i do. If i compile this sources, will i have an android image? Could you help me or give some information? I would like to add cmex81's usbtouchscreen.c file and do an android image file of 4.4.2 version. Any help greatly appreciated.
Just so you know: we're going to shift soon to UDOObuntu 2 stable (Kernel 3.14.56 Ubuntu 14.04 LTS) also for UDOO Quad: https://github.com/UDOOboard/linux_kernel
