[linux-dvb] Re: DiBcom DVB-T USB and frontend driver (Twinhan,KWorld, Hama)

Hi Patrick,

as soon as I've read about your new driver, I've downloaded the CVS
dvb-kernel and tried it.
After making a symlink(from dibusb.c to dvb-diusb) it compiled
clean(Bug?).
But I couldn't get it working. Plugging in the device, hotplug loads the
driver and the device powers on. After manually loading the frontend
module, I was able to run all dvb tools.
Running scan I got the following:

Done.

I had similar experiences with the first driver but this time I even got
no signals from the 3 status LEDs(using the first driver, they flashed
shortly).

Also tzap doesn't work. The output is:

using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'

status 1f | signal d780 | snr 4015 | ber 00000000 | unc 00000000 |

....

But there's no LED activity at all.
