Chinese $10 capture card quality silicon... :-)

FWIW I tried stopping and starting the stream repeatedly and the 
workaround seems to be reliable. I also checked the packets with usbmon 
to confirm that there is no weirdness in the driver, it's really how the 
data comes in from the very first isoc packet sent by the hardware.
