[mythtv-users] HD-PVR power cycling

[Andrew Stadt]

Again, sorry about the top post... can't get this phone to do anything else.

On the flakey machine have you tried plugging the hd-pvr into an external (powered) usb hub?  The only reason I throw this out there is I have had a few other usb devices (CommandIR II for eg) that simply will not work, or are shall we say toublesome, with some usb subsystems in 64 bit mode but work fine with a 32 bit kernel (or vice versa) but work fine with a hub between the computer and the device.

Just a thought,

Andrew.

As another data point - I have two HD-PVRs and two backends - one is rock
solid, the other one is super flaky.  Here's the kicker though, it appears
that the issue is more with the backend hardware than with the HD-PVR.

If I swap which machine each HD-PVR is hooked up to, the same backend is
still rock-solid and the other one is still flaky.  The stable one is an
older AMD box, and the unstable one is a newer Intel box.  They're running
basically the same custom kernel (with a few different drivers for HD
controllers etc)

The conclusion that I'd come to is that the Intel chipset's USB drivers
weren't playing nicely with the HD-PVR, but I haven't had a chance to do
more digging on it beyond that.
