[pvrusb2] Random hang during 'modprobe -r pvrusb2'

[devsk]

Mike,

This is with 2.6.34.1 and latest driver snapshot:

[18693.055000] pvrusb2: 20100708 (from www.isely.net):Hauppauge WinTV-PVR-USB2 
MPEG2 Encoder/Tuner

I did modprobe -r pvrusb2 and it hung.

This is what it shows in dmesg:

[32118.444000] usbcore: deregistering interface driver pvrusb2
[32118.444000] pvrusb2: Device being rendered inoperable

Its still hung here. How can I collect more information for you to debug this 
issue. Its very intermittent. So, since we have it hung there, this is our 
chance to nail this bugger.

Thanks,
-devsk
