Dvico Dual Express 2



Hi,

I've recently obtained a Dvico FusionHDTV DVB-T Dual Express2, and
found it is not the same card as the Dual Express. There is a chance
I've done something particularly silly, but I've tried specifying card
types etc, and so far had no luck. I believe this is a new hardware
revision and currently unsupported. I've made a quick note on the
wiki, but I wasn't sure if I should create a new page separate from
the existing info page in the Dual Express. From memory the card looks
identical to the pictures at
http://www.linuxtv.org/wiki/index.php/DViCO_FusionHDTV_DVB-T_Dual_Express.

My dmesg looks like:

Loading the module with card=11 (looks like the most obvious choice) shows:

I've tried a few different card types to see the results, but nothing
much more promising than that.

Is anyone familiar with this board? Any chance anyone has been
tinkering with it?

It seems like the DVICO dual express cards being shipped now might all
be this new revision, so it might be worth spending a bit of time on.
I'm happy to assist with more information if anyone is interested,
otherwise I think I'm going to have to do a whole lot of reading (and
tinkering).
