A DVB-T 34/54mm Express Card from AVerMedia.

It is currently not supported under Linux (Dec 2012).

Does not work out of the box, but can be correctly detected after source files update and compilation.

Remaining problem: couldn't get any working frequency/transponder.

Workaround

As long as 'modinfo dvb_usb_af9035 | grep v07CAp0918' is empty, compilation of af9035.c and dvb-usb-ids.h with patch above is necessary:

'modinfo dvb_usb_af9035' should report:

A918R tuning is then not working as expected.

Comments

1] still some doubt on exact dvb-usb-af9035-02.fw firmware to be used (several LINK/OFDM versions tested)

2] AVerTV_Volar_HD_PRO_A835 using same components is reported to work with some experimental tweaks.

Then still some hope, but no solution identified by now.
