While I can't say so with certainty since I don't know how to monitor
its internal temperature, I doubt that it's heat related in my case. I
see the same failures when the HD PVR has been idle for hours after
the original successful recording and the ambient temperature is
around 55 degrees F.

I did indeed try the latest Hauppauge update, but it doesn't seem to
have actually changed anything with the HD-PVR itself. dmesg still
reports '0x12' when I load the module and recordings still fail in the
At this point I've tried every voodoo computing solution I can think
of - different kernel versions, different USB cables, different USB
ports, turning the HD PVR upside down, doing the hokey pokey and
turning myself around... and the device still fails to start
I'm starting to think that the device is defective in some subtle way
since it doesn't seem as if anybody else is seeing an identical
pattern. Has anybody tried RMAing one of these units with Hauppauge? I
wonder what the process would look like. I suppose my next step will
be to hook it up to a Windows box and see if it fails in the same
manner, since I'm guessing Hauppauge won't support its use under
