The op mentioned that he also had an APC UPS device
that hung at the same time (although if I interpreted
the posting correctly, that one recovered after the
machine reboot; maybe it was not as confused and
dazed as the pvrusb devices and was able to be
reinitialized at boot).

AFAIK the APC device does not use the V4L subsystem
(although you can never tell, APC is working at doing
entire DC management, and maybe this one takes
video/pictures of the site).

So, I am sticking with my WAG.
