I think you are right. I will try snooping the device under Windows
and comparing things to see if I can find anything. I am surprised
though that no one can tell me what the different colour LEDs
represent on the front of the device.

One thing that I have noticed is the following message when the driver
is loaded:

[  783.248000] ttusb_probe: TTUSB DVB connected
[  785.168000] ttusb_init_controller: stc-version: V 2.5
[  785.168000] ttusb_init_controller: unknown STC version V 2.5, please report!
[  785.168000] ttusb_init_controller: dsp-version: 0.0
[  785.172000] DVB: registering new adapter (Technotrend/Hauppauge Nova-USB).
[  785.196000] DVB: registering frontend 0 (ST STV0297 DVB-C)...
[  785.196000] ttusb_probe: TTUSB DVB connected
[  785.196000] usbcore: registered new interface driver ttusb

Would this be an appropriate means of "reporting it"? If anyone would
like further info or debugging to be run, please let me know.
