Liplianin Hi Igor, I have a brandless DVB-S tv tuner card also, with a dm1105n chip. I was getting the "DM1105: could not attach frontend 195d:1105" message with the latest kernel also, but I applied this patch to the dm1105 module and now the card's being recognised (though is still listed as an ethernet controller with lspci) My dmesg output is: dm1105 0000:01:05.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 DVB: registering new adapter (dm1105) dm1105 0000:01:05.0: MAC 00:00:00:00:00:00 DVB: registering adapter 0 frontend 0 (SL SI21XX DVB-S)... Registered IR keymap rc-dm1105-nec input: DVB on-card IR receiver as /devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0/input6 rc0: DVB on-card IR receiver as /devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0 The card is one of these: http://www.hongsun.biz/ProView.asp?ID=90 Scanning doesn't appear to give me any results. Should this be working? Anything I can do to test the card out for you? Cheers, Matt.
