gspca webcam: need to plug it 5 times before it works

[Pavel Machek]

Hi!

..but if I'm patient enough, it eventually starts working... somehow.

Incoming data seems to go in reliably. Outgoing commands (such as
change gain) don't seem to be unreliable.

Any idea how to debug / what could be wrong?

Thanks,
								Pavel
