I don't have. I have a few Terratec DVB-C devices here with DRXK, using different
bridge drivers. I started looking on them based on a released DRXK driver, but, as
Oliver already had some work on the drxk driver, it is better to merge Oliver series
first and then I start working on adding DRXK support to the other drivers, to avoid
duplicated work at the DRXK drivers.
