Hi Greg
now i splittet the patch into two part
1. part : Simulate a pressure for tslib(input-raw)
2. part: Fix the urb->transfer_flags/dma (as done in hid-core.c)

This patch simulates a pressure to the input sub-system
when touchscreen is touched. With this Patch the input-raw
plugin from tslib can be used without modification.

This patch corrects the URB initialisation for transfers
like this is done in other drivers too.
Without this patch no data was transmitted on a PXA270 OHCI
platform. May apply to others too.
