Hi,

the tuning problem is solved, now!
Patrick Boetcher realized that the dvb-usb-wt220u-01.fw firmware file from 
http://www.linuxtv.org/downloads/firmware/
actually contained the dvb-usb-dtt200u-01.fw firmware.

The Yakumo QuickStick requires the dvb-usb-wt220u-01.fw!

The corresponding md5sums of the firmware files are here:
d68d6ad6b6eebf7e4435935c1bbaf313  dvb-usb-dtt200u-01.fw
782c9937b3f42e5248584570857c8b7f  dvb-usb-wt220u-01.fw

So please check in case of problems.

Until the archive is updated you can find the correct
dvb-usb-wt220u-01.fw firmware here:
http://www.linuxtv.org/cgi-bin/viewcvs.cgi/*checkout*/dvb-kernel/firmware/dvb-usb-wt220u-01.fw?rev=1.1


Cheers,

Frank
