Hi,

I did enable the event debuging in the kernel, when i touch the touchscreen i've got:

system log:
	<7>evbug.c: Event. Dev: <NULL>, Type: 3, Code: 0, Value: 354
	<7>evbug.c: Event. Dev: <NULL>, Type: 3, Code: 1, Value: 479
	<7>evbug.c: Event. Dev: <NULL>, Type: 3, Code: 24, Value: 228
	<7>evbug.c: Event. Dev: <NULL>, Type: 0, Code: 0, Value: 0
	<7>evbug.c: Event. Dev: <NULL>, Type: 3, Code: 24, Value: 0
	<7>evbug.c: Event. Dev: <NULL>, Type: 0, Code: 0, Value: 0 

Why is the device string <NULL>, in case of the mouse is the correct mouse specified.

Part of the kernel bootmessages indicating that there is a touchscreen:
	input: Logitech USB-PS/2 Optical Mouse as /class/input/input0
	input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-pxa27x-1
	usbcore: registered new interface driver usbhid
	drivers/hid/usbhid/hid-core.c: v2.6:USB HID core driver
	Advanced Linux Sound Architecture Driver Version 1.0.14 (Fri Jul 20 09:12:58 2007 UTC).
	pxa2xx_ac97_reset: cold reset timeout (GSR=0x0)
	input: UCB1400 touchscreen interface as /class/input/input1
	ALSA device list:
  #0: pxa2xx-ac97 (Philips UCB1400)

Thanks for any remarks!

Best regards,

Henk
