Hi,

I am porting a 7" LCD on i.MX53 QSB with capacitive touchscreen. I am under ANDROID. The touchscreen has an USB interface and is recognized during kernel boot :

 

input: eGalax Inc. USB TouchController as /devices/platform/fsl-ehci.1/usb1/1-1/1-1:1.0/input/input0
generic-usb 0003:0EEF:7304.0001: input: USB HID v2.10 Pointer [eGalax Inc. USB TouchController] on usb-fsl-ehci.1-1/input0

 

When i press on the touchscreen there are no movements.

With getevent, all interrupts are detetected :

 

# getevent
could not get driver version for /dev/input/mice, Not a typewriter
add device 1: /dev/input/event0
  name:     "eGalax Inc. USB TouchController"
could not get driver version for /dev/input/mouse0, Not a typewriter
/dev/input/event0: 0003 0002 00000616
/dev/input/event0: 0003 0003 00000492
/dev/input/event0: 0000 0000 00000000
/dev/input/event0: 0004 0004 00090001
/dev/input/event0: 0001 0110 00000001

...

 

Any idea ?

 

Thanks.

Xavier
