I have a Technotrend CT2 4650. It worked perfectly on a Ubuntu 16.04.02, which was a upgrade from the previous LTS line as far as I remember. The USB module was dvb_usb_dvbsky.
Then my SSD crashed, and I reinstalled 16.04.02 the other day. It's not discovered anymore. It's shown in lsusb of course, but the module does not seem to initialize it:
Bus 001 Device 003: ID 0b48:3015 TechnoTrend AG
When I modprobe dvb_usb_dvbsky, this appears in dmesg:
[ 175.468458] usbcore: registered new interface driver dvb_usb_dvbsky
I have tested the module on a PC running OpenSuSE, and the following turned up in dmesg:

As far as I can remember, this is more or less what turned up on the previous Ubuntu install as well - I particularly remember seeing the initialization of the CAM...
I have tried insmodding the required modules manually, with no result.
This is what appears in dmesg when I plug the USB cable to the device, with relevant modules loaded:
[ 3285.678512] usb 1-1.1: new high-speed USB device number 6 using ehci-pci
[ 3285.776059] usb 1-1.1: New USB device found, idVendor=0b48, idProduct=3015

[ 3285.776076] usb 1-1.1: SerialNumber: 20151107
Compared to OpenSuSE (and previous Ubuntu install) it's not much.
Any pointers are welcome.
