%description
A Linux kernel module for Thrustmaster T300RS, T248, and experimental support
for TX, T128, T598, TS-PC and TS-XW racing wheels.

This package provides force feedback support and advanced features for supported
Thrustmaster racing wheels. The driver includes wheel initialization modules
(hid-tminit) and the main force feedback driver (hid-tmff-new).
