I am aware that there is some development going on for the saa7164 driver to support the Hauppauge WinTV-HVR2205. I thought I would post some feedback. I have recently compiled the driver as at 2015-05-31 using "media build tree". I am unable to tune a channel. When running the following w_scan command: w_scan -a4 -ft -cAU -t 3 -X > /tmp/tzap/channels.conf I get the following error after scanning the frequency range for Australia. ERROR: Sorry - i couldn't get any working frequency/transponder Nothing to scan!! At the same time I get the following messages being logged to the Linux console. dmesg [165512.436662] si2168 22-0066: unknown chip version Si2168- [165512.450315] si2157 21-0060: found a 'Silicon Labs Si2157-A30' [165512.480559] si2157 21-0060: firmware version: 3.0.5 [165517.981155] si2168 22-0064: unknown chip version Si2168- [165517.994620] si2157 20-0060: found a 'Silicon Labs Si2157-A30' [165518.024867] si2157 20-0060: firmware version: 3.0.5 [165682.334171] si2168 22-0064: unknown chip version Si2168- [165730.579085] si2168 22-0064: unknown chip version Si2168- [165838.420693] si2168 22-0064: unknown chip version Si2168- [166337.342437] si2168 22-0064: unknown chip version Si2168- [167305.393572] si2168 22-0064: unknown chip version Si2168- Many thanks to the developers for all of your hard work. -- 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
