Hi all,
i try to arrange some codes, and named "usbtouchdev",
wish to help merging all USB touchscreen devices like
mtouchusb.c, itmtouch.c, touchkitusb.c, usbtouchset.c, etc.
in this moment, only add my touchscreen driver here and test pass.
if anyone wanna add another USB touchscreen driver, or wanna modify the codes,
or any help i can do, please feel free to tell me.
wish help some.
