[linux-dvb] Technotrend common interfaces think my CAM is invalid

A while ago I compiled and installed a new v4l-dvb. After that, my 
common interface never worked correctly again. Not long after installing 
the v4l-dvb, the PSU in my computer broke down, most likely coincidence. 
After replacing the PSU the computer worked again. I've got both a TT 
S-1500 and T-1500 with CI.

But the common interface still fails. So I:

*Installed the newest v4l-dvb today
*Tried 2 other CI cables
*Tried swapping the CI daughterboards (one 1.0a and one 1.1)
*Tried another computer with different mainboard and (much) older 
v4l-dvb (Ubuntu 6.10)
*Blew the dust off my TT S2-3200 (never used before), connected the CI 
to it and installed multiproto few weeks ago
*Decided my old PSU must have blasted both CI daughterboards, ordered 
new ones and installed that with v4l-dvb downloaded today
*Re-installed the linuximage package (Ubuntu 7.10) (but not sure if all 
v4l-dvb from hg is removed with that)

Maybe I've tried more but I don't remember right now. Anyway, nothing of 
this helped. My official CanalDigitaal/TV Vlaanderen Mediaguard module 
and Xcam give me "dvb_ca adapter 0: Invalid PC card inserted :(". Only 
my Matrix Reborn initializes, but does not work correctly (corruption 
and/or decodes only audio PID and not video and/or just acts weird). 
Offical Conax 4.00e is not working so well anymore either (does not 
always initialize correctly), but atm I've got no subscription card to test.

In a standalone Vantage receiver, all modules work well. So they can't 
be invalid. I just watched Mythbusters with the offical Mediaguard 
module. And they used to work on the TT, I only remember from the past 
that the offical Mediaguard gave some corruption (it's compatiblity is 
not great) but it did run. According to some linuxtv wiki this CAM 
should now work fine.

I'll go look for some Knoppix and see if my CAMs initialize correctly 
with that. This is really strange. If anyone's got a clue..
