To get this close to working I have: 1) Added 50-udev.rules which seem to allow the device to be recognised. 2) Compiled the ~jhoogenraad/rtl2831-r2 version of the driver. This gets me to the point where: - /dev/dvb exists. - my applications recognise the device - In the log I see: [ 14.311735] dvb-usb: found a 'VideoMate U90' in warm state. [ 14.311743] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer. [ 14.312131] DVB: registering new adapter (VideoMate U90) [ 14.312420] DVB: registering adapter 0 frontend 0 (Realtek RTL2831 DVB-T)... [ 14.312521] input: IR-receiver inside an USB DVB receiver as /devices/pci0000:00/0000:00:02.1/usb1/1-1/input/input5 [ 14.312552] dvb-usb: schedule remote query interval to 300 msecs. [ 14.312558] dvb-usb: VideoMate U90 successfully initialized and connected. [ 14.312589] usbcore: registered new interface driver dvb_usb_rtd2831u So looking good so far. However, if i used scan, or an application like Kaffeine tuning fails. I know that the device works as I can get it to work on windows. So I have been looking at the RTL2831U data sheets which I know from the windows driver that this is based on. (I don't know much about this hardware I am trying to figure it out ). So this chip is just doing the demodulating and the USB interface. It must therefore be paired with tuner. It seems logical to me (but is possibly wrong ) that if the demodulator is working and I cant tune, then the issue is with the tuner part of the driver. The windows drivers refer to both the MT2060 and the QT1010, but I don't know which one is being used. (I have not had the guts to rip the thing apart yet). Docu in the code of for the driver implies that it can support the MT2060 but not the QT1010 so I guess with my luck it is the quantec one. Has any one got any advice as to where I should look next? Has anyone got this to work? It seems to be quite close. I any suggestions would be appreciated.
