[media] [1/2,ver,1.89] DM04/QQBOX Interupt Urb and Timing changes
Reduce buffer size of Interupt urb to 128 bytes and polling interval to 8. The devices buffer appears to only handle a maxium of 40 bytes. If the buffer is full a slowing effect is noticed causing occasionnal dropped streaming packets.
