make in v4l-dvb worked without error, produced a lot of .ko files in v4l. sudo make install worked without errors, too. reconnecting the TechnoTrend CT 3650 CI, with dmesg I got --- usb 4-2: USB disconnect, address 3 usb 4-2: new high speed USB device using ehci_hcd and address 6 usb 4-2: configuration #1 chosen from 1 choice usb 4-2: New USB device found, idVendor=0b48, idProduct=300d usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 4-2: Product: TT-USB2.0 usb 4-2: Manufacturer: TechnoTrend usb 4-2: SerialNumber: LHKAMG --- and thought, dvb_usb_ttusb2 would be the driver to load. However, neither /dev/dvb0 nor /dev/video0 appeared following "sudo modprobe dvb_usb_ttusb2". Restart of linux did not help and did not reload dvb_usb_ttusb2. I know it worked once but forgot, how. And it seems that it works with some others: http://www.linuxtv.org/pipermail/linux-dvb/2008-August/027804.html How to determine what driver I need? Do I need firmware?
