I have been looking at the vp702x driver and I can't
seem to match the commans up against a USBSnoop that I
have done on a windows machine when tuning the card.
Apparently the linux driver is alpha and doesn't work
so I thought that there might be something that I
could figure out. Does anyone have any documentation
to share on this card?
I'm interested in what the following packets mean:
