The patch contais modifications of Antti's rtl28xxu driver and a modified version of the fc0012 driver from Hans-Frieder Vogt posted recently on this list. The driver as of now just implements the bare minimum to be working. The features I plan to add next are: - Remote control - Signal quality readings - Hardware PID filtering I tested the driver with the Terratec Cinergy T Stick Black, which is the only device supported so far.
