Hi Mauro, drxk driver seems to have 2 issue with w_scan: - dvb-t tune error while scanning ("solved" by forcing w_scan to open dvb-t fe without autoscan) - dvb-t scan fail so... we should have an issue that when the driver release dvb-c adapter drxk (or xc5000?) stay in dvb-c mode Can you check if you can replicate my error and if Terratec H5 have same issue? follow the test:.... I build w_scan 20111011 like you -unplug tuner -replug tuner dmesg says: [ 1030.370462] DVB: registering new adapter (em28xx #0) [ 1030.370470] DVB: registering adapter 0 frontend 0 (DRXK DVB-C)...

However, like Fedrik, I don't get errors on dmesg but w_scan ends with ERROR: Sorry - i couldn't get any working frequency/transponder Nothing to scan!! - w_scan -a /dev/dvb/adapter0/frontend1 -I it-All no error on dmesg... - w_scan -f t -c IT Leaving autodetect turned on I get [ 794.964818] drxk: Error -22 on QAMSetSymbolrate [ 794.964827] drxk: Error -22 on SetQAM [ 794.964832] drxk: Error -22 on Start [ 795.164518] drxk: Error -22 on QAMSetSymbolrate [ 795.164528] drxk: Error -22 on SetQAM [ 795.164534] drxk: Error -22 on Start trying scan now... scan -f1 it-All dmesg days [ 2044.103987] drxk: Error -22 on Start [ 2045.293728] drxk: Error -22 on SetQAM [ 2045.293738] drxk: Error -22 on Start [ 2045.431231] drxk: Error -22 on QAMSetSymbolrate [ 2045.431241] drxk: Error -22 on SetQAM [ 2045.431246] drxk: Error -22 on Start regards, Eddi -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
