Approximately a year ago I tried to make this USB DVB-T box work. But it 
wouldn't. With a little more knowledge today I tried again with v4l-dvb 
from hg, but it still won't go. I get this when I plug it in:

[ 3083.152125] usb 1-2: new full speed USB device using ohci_hcd and 
address 4
[ 3083.253055] usb 1-2: configuration #1 chosen from 1 choice

USB Driver successfully initialized and connected.

Note the "CX24123: wrong demod revision: 0". What's with that? It looks 
like something is wrong.

I get this when I unplug it:

I think it doesn't like being unplugged. The problem is still the same: 
I see the device in /dev/dvb and in Kaffeine, when I try to watch a 
channel I see the ACT LED on the device blink a bit, but the LOCK LED 
will never light up and I never get to watch anything. Using Ubuntu 8.04.
