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.

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'm sorry -- I forgot to include the link to the pvrusb2 web page:


Also, I think I may have been unclear in my previous email.  Basically, the information that you've shown us is not enough to indicate any problem, nor is it enough to indicate success.

The most common and likely reason that it might not be working is for lack of the "v4l-pvrusb2-73xxx-01.fw" firmware, but that is only a guess based on the incomplete information.

If you still cant it working, please show us a full dmesg dump.

I hope this helps...
