[mythtv-users] hdpvr won't record through myth

Wed Apr 2 00:07:57 UTC 2014

Have 2 SBEs, each with a hdpvr attached.  One works, the other doesn't.
Trying to figure out what's wrong with the 2nd.  I can do a cat /dev/video0
> it.mpg and it works fine.  But the SBE recordings fail with poll timeout
(full logs below).  After myth tries to use the device, cat fails until I
rmmod/modprobe the driver again to get cat to work.

Things I've tried/confirmed:
- Same hdpvr firmware on both working and not working:   1.7.1
- Disabled usb 3.0 in bios (per another thread)
- Same kernel versions on both 3.10.7;  have now upgrade the non-working to
3.10.34

Running on gentoo v0.27-196-g3ca3f6d but I had this issue with .26 as well.

I'm totally stumped at this point. Thanks in advance
