My Gigabyte U7000-RH was working until last night when I upgraded to a new kernel build -I'm running Ubuntu 8.04 and (now) 2.6.22-15-generic. :-( Since then the device can't tune and I don't know how to troubleshoot the problem. :-( I've tried re-making and and re-installing the the v4l-dvb. I've tried hg-ing a new clone from http://linuxtv.org/hg/v4l-dvb (and remaking & re-installing). I've tried 'make rminstall' and 'make distclean' followed by 'make; sudo make install'. I've placed a copy of the firmware in /lib/firmware/2.6.22-15-generic/ When I connect my dvb-t dongle /var/log/messages look fine: ------------------------------------------------------------------------ Jul 2 08:55:12 squash kernel: [ 491.125748] dvb-usb: found a 'Gigabyte U7000' in cold state, will try to load a firmware Jul 2 08:55:12 squash kernel: [ 491.143173] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.10.fw' Jul 2 08:55:12 squash kernel: [ 491.225304] dib0700: firmware started successfully.
