Thank you very much for your response, i am really hopeless.
I tried so many combinations of kernel config options, but no result. In
Froyo I just compile kernel with added CONFIG_HID_QUANTA=y and it worked.
I thought that kernel should create input for the touchscreen if there is
right driver present - I mean that it is the first place where i have
something wrong, because it doesn't create any input.
In dmesg it found only one squirk - maybe it is the problem.
This is my current (not working) HID configs panda_defconfig file
CONFIG_HID_QUANTA=y
CONFIG_HID=y
CONFIG_USB_HID=y
CONFIG_HID_MULTITOUCH=y
CONFIG_HID_SUPPORT=y
CONFIG_HIDRAW=y
CONFIG_HID_PID=y
CONFIG_USB_HIDDEV=y
Do you have any idea what could be wrong?
Which version of ICS you were working on?
Thank you
Jiri
