I'm trying to use a different touchscreen in android. The touchscreen is connected via USB and recognized as a HID device but it does not work. Even enabling the display of positions I do not see events on the screen (wich is 1280x800). When the screen goes into standby the touch does not wake it up (but if I connect a USB mouse I can interact with the system). I can not understand what is not working. The kerner detects the device:

input: HID 03eb:214e as /devices/platform/fsl-ehci.1/usb2/2-1/2-1.3/2-1.3:1.1/input/input2

Android EventHub also:

I/EventHub( 2499): New device: id=2, fd=92, path='/dev/input/event2', name='HID 03eb:214e', classes=0x80000004, configuration='/system/usr/idc/Vendor_03eb_Product_214e.idc', keyLayout='', keyCharacterMap='', builtinKeyboard=false

Android InputReader too:

I/InputReader( 2499):   Touch device 'HID 03eb:214e' could not query the properties of its associated display.  The device will be inoperable until the display size becomes available.
I/InputReader( 2499): Device reconfigured: id=2, name='HID 03eb:214e', size 1280x800, orientation 0, mode 3, display id 0

Android pointer show those messages:

Using getevent -l and touching the upper left corner I have this output:

If instead I touch the lower right corner:

/dev/input/event2: EV_MSC       MSC_SCAN             000d0042

/dev/input/event2: EV_KEY       BTN_TOUCH            DOWN                
/dev/input/event2: EV_MSC       MSC_SCAN             000d0042            
/dev/input/event2: EV_KEY       BTN_TOUCH            UP                  
/dev/input/event2: EV_ABS       002d                 00000055

/dev/input/event2: EV_SYN       SYN_REPORT           00000000

In the input device configuration file "/system/usr/idc/Vendor_03eb_Product_214e.idc" there are those lines:

device.internal = 0

touch.deviceType = default
touch.orientationAware = 1

I hope someone can help me understand what I'm doing wrong!

Thanks in advance!
