Hi there,

I've got the following card: http://www.twinhan.com/product_cable_2033.asp

I am running Ubunu 7.10 with kernel 2.6.22-14-generic

I have compiled and installed the latest drivers from http://jusst.de/hg/mantis and it seems to detect the card correctly but when scanning for channels it fails.
The card works correctly in windows.

This is what dmesg gives me:
...
[ 4022.137802] found a VP-2033 PCI DVB-C device on (05:05.0),

[ 4022.658243] DVB: registering frontend 0 (Philips TDA10021 DVB-C)...
...

When trying to scan it simply gives me the following result:

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Is there any way i can debug the driver to see where it goes wrong?
If there is anything i can do, I would be glad to help out.

Any help would be greatly appreciated.

Best regards,
Rikard Wissing
