The strings in the driver do not tell you much about the real hardware 
inside.. Do you have a picture of the device somewhere? Can you open the 
device and have a look at the ICs used?

Indeed there is/will be a device around with ULI USB bridge and DiBcom 
demodulator, but I don't know when.

The problem is, that the ULI USB bridge is not supported by OpenSource 
drivers. When they claim Linuxsupport, they maybe provide a binary driver 
or it was just a marketing gag :).

Sorry to tell you that,
