Dear forum members,
the same CFA-635 I had mentioned in my previous post now sits happily in a wooden enclosure. The same enclosure houses a computer - actually, the whole case. There are some fans and air filters to keep the interior cool and free of dust, but otherwise, there is nothing. I did a test run with a laptop, where the setup ran fine with lcdproc for about a day. Now, with the computer inside and the TFT's USB connected to it, it won't display a thing. Instead, I get the following messages in my kernel log:
I already tried changing the ports, but to no avail. So I'm wondering whether it could really be EMI. The CFA-635 has everything attached that would be needed to place it in a 5.25" drive bay, but the back is "exposed" to the interior of the case. (But the computer standing there is still in its original casing.) Does the TFT need some sort of Faraday's cage? Or are any other USB issues known that could be it? Google didn't help me find anything.
Thanks a lot in advance for any hints.
