Hi all
--This is time,I paste the patch into my email directly.
There is a problem,that is,the coordinate of Generaltouch touchscreen is limited to 0xFFF by usbtouchscreen.c while many models of our touchscreen give bigger coordinate than that.Could you please apply this patch to linux kernel?
Thanks!
