Hello All

I did add some more debug messages. The call for 
"(ves1820_readreg(state, 0x1a) & 0xf0)" in "ves1820_attach" does return 
0xf0 and not 0x70!?

That's the reason why I get the "dvb-ttusb-budget: A frontend driver was 
not found for device 0b48/1004" message. So what to do next?

Here are the logs:
