Thanks a lot for your response. On PC (Ubuntu 12.04) also, channel list is not seen. I saw a youtube video (http://www.youtube.com/watch?v=lv-Hel3DUkY) that Prof USB 7500 DVB-S2 device works.
Looks like driver is trying to lock at the frequency which is out of range of what driver is expecting (950000...2150000) -----Original Message----- From: Oliver Schinagl [mailto:oliver+l...@schinagl.nl] Sent: Wednesday, July 24, 2013 5:49 PM To: Krishna Kishore Cc: linux-media@vger.kernel.org Subject: Re: Prof DVB-S2 USB device On 24-07-13 13:31, Krishna Kishore wrote: > > Any idea on the following error? > > scanning /stbref/dvb-apps-f3a70b206f0f/util/scan/dvb-s/Insat4B_C-93.5E > using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' > initial transponder 3725000 H 27500000 3 initial transponder 3750000 H > 4250000 3 initial transponder 3762000 H 4250000 3 initial transponder > 3768000 H 4250000 3 initial transponder 3774000 H 4250000 3 initial > transponder 3802000 H 4250000 3 initial transponder 3808000 H 4250000 > 3 initial transponder 3822000 H 4250000 3 initial transponder 3832000 > H 6250000 3 initial transponder 3841000 H 6250000 3 initial > transponder 3885000 H 28000000 3 initial transponder 3925000 H > 27500000 3 initial transponder 3950000 H 4440000 3 initial transponder > 4005000 H 25422000 7 initial transponder 4045000 H 28000000 3 >>>> tune to: 3725:h:0:27500 > DVB-S IF freq is 6025000 > [ 3095.402008] DVB: adapter 0 frontend 0 frequency 6025000 out of > range (950000..2150000) > __tune_to_transponder:1910: ERROR: Setting frontend parameters failed: > 22 Invalid argument No idea, but I wouldn't be supprised if it is a new version of w_scan, and an old driver ;) >>>> tune to: 3725:h:0:27500 > > > ________________________________________ > From: linux-media-ow...@vger.kernel.org > [linux-media-ow...@vger.kernel.org] on behalf of Krishna Kishore > [krishna.kish...@sasken.com] > Sent: Wednesday, July 24, 2013 4:50 PM > To: Oliver Schinagl > Cc: linux-media@vger.kernel.org > Subject: RE: Prof DVB-S2 USB device > > On Desktop PC (Ubuntu 12.04 which has 3.2.0 Kernel) also, I am not getting > the list of channels when I scan.
