I'm trying to bring-up the CinergyT2 USB DVB-T receiver module within

descriptors show a strange

endpoint 0x82 (input-bulk 64 bytes).
The problem is that number of endpoints is set to 0x02 in the descriptor
In some mailing-list I've seen a reference to firmware version 1.03; but
this seems to be not available (anymore).
Has anybody had a similar problem ? Is it a device problem ? Can I
workaround by patching the USB core driver to
