Hi Im having errors with compiling in usbtouchscreen.c into the kernel drivers. I have attached the usbtouchsreen.c file to the post also.

 CC      drivers/input/touchscreen/usbtouchscreen.o
drivers/input/touchscreen/usbtouchscreen.c: In function 'usbtouch_free_buffers':
drivers/input/touchscreen/usbtouchscreen.c:856: error: implicit declaration of function 'usb_buffer_free'
drivers/input/touchscreen/usbtouchscreen.c: In function 'usbtouch_probe':
drivers/input/touchscreen/usbtouchscreen.c:890: error: implicit declaration of function 'usb_buffer_alloc'
drivers/input/touchscreen/usbtouchscreen.c:891: warning: assignment makes pointer from integer without a cast

make[2]: *** [drivers/input/touchscreen] Error 2

Is your driver quite old (or for an older kernel, perhaps)? Perhaps you want to take a look at this rename:

It seems to be in the latest kernel at least:

In fact it seems to have gone into 2.6.34 or thereabouts.
