Hi Nick, thanks for this nice patch. I'm not in charge of committing that (don't know the uli-thing very well), but I would like to comment: On Wed, 21 Mar 2007, Nick Andrew wrote: > Here's my patch so far. > > Two remaining problems: > > > 1 - device is probed twice and I end up with 4 /dev/dvb adapters > rather than two.

If the device is working OK like that, your workaround is good. I assume that the ULI/Lifeview people didn't want to spend much time to create an architecture for their Windows driver, which supports multiple BDA-filters per device. So they changed the USB-descriptor so that their driver is called twice so that they can do the second receiver.
