Yet, if I boot without it and plug it in after boot, the drivers (pvrusb2 et al) seem to load, but no device nodes are created.  I have downloaded the firmware, renamed it properly, and placed it in /lib/firmware.  So I'm at a loss on how to troubleshoot.  Here's the relevant information on plug-in the box in after the system has been booted.

What firmware did you " download and rename " ??

Where did you get " v4l-pvrusb2-73xxx-01.fw " ??  or did you forget it?

Those lines will show up is you simply "modprobe pvrusb2" even if the device is not present.  What comes next?  It should download firmware, disconnect & reconnect USB automatically, then continue on with driver initialization.

lsmod doesnt tell us anything.  You can load all those modules by hand, and it says nothing about the device that you have plugged in.

Unfortunately (and I assume this is another Ubuntu problem) I can't unload pvrusb2 once loaded.  It hangs the terminal.  It makes playing around with it a tedious endeavor.

I think you're best off taking a look at the pvrusb2 home page and reading the information there.  If you are still having trouble, then please just paste your full dmesg into an email so that we can have a better idea of what's wrong.

Good Luck,
