Martin,
I am investigating a simillar (but not the same) problem with a TT-3200
and a T-Rex/Dragon CAM (see my postings in the last week). I am
beginning to come to the conclusion that either I have a hardware
problem or the TT-3200 does not like certain CAMs, this is partially
born out by the fact the some incompatible cams are listed on the wiki
http://www.linuxtv.org/wiki/index.php/DVB_Conditional_Access_Modules . I
don't know whether this is a hardware or software (or both)
incompatibility. If it software it could be fixable. Does anyone know?
I did come across a post, which I have been unable to find again! This
referred to the fact that the Dragon CAM was asserting a line on PCMCIA
interface that said it was a low voltage device (3.5V) and that this was
outside the CI spec and causing a problem with the budget CI.
However this link says that it should work. I don't know if your CAM is
on it. I suspect this is referring to the supplied windows driver
http://www.dvbnetwork.de/index.php?option=com_fireboard&func=view&id=927&catid=2&Itemid=26
I would love to investigate further but really need some specs of the
software interface to the 3200. Can anyone point me at further info? All
I have at the momenet is the spec for the SAA7146 chip and the en50221
CI spec.
Sorry I cannot offer any direct help. But I thought you might like to
know you are not the only one fighting with this piece of hardware :-)
