Hi,
I have an ASUS EeeTop ET1602, with touchscreen id (1bfd:1688).
Originally it works fine with kernel 2.6.32,
but now it doesn't work since kernel 2.6.35 (maybe?).

I made some investigation.
I think it's related to this patch:

    HID: use multi input quirk for TouchPack touchscreen

    This device generates ABS_Z and ABS_RX events, while it should be
    generating ABS_X and ABS_Y instead. Using the MULTI_INPUT quirk solves
    this issue.


Could you explain what's the patch intend to do,
and how could I solve the problem?

It depends on your userspace. It should work properly with X.org drivers
evdev and evtouch. Are you trying this with Android?
