Well there must be something in that distro that auto-unzips modules as 
they are needed.  First I've ever heard of that, though it does make 
some sense to have something like that.

You won't find any such thing in the log.

What is *supposed* to happen is that the USB ID of the device should 
trigger the loading of the pvrusb2 module.  Once loaded, the pvrusb2 
module is logically attached to the pvrusb2 module and everything works.

Everything you've described to this point suggests that your device is 
not being associated with the pvrusb2 module.  This is surprising since 
the device you are trying to run has worked with the pvrusb2 module for 
quite some time.  The kernel version you listed should have been recent 

I just realized something here, and I'm sorry I didn't realize this 
earlier.  You're running an OnAir GT?  That is an entirely different 
device, not supported by the pvrusb2 driver.  That would explain 
everything you've observed.
