USB: increase cdc-acm write throughput
the following patch uses 16 write urbs and a writsize of wMaxPacketSize
* 20. With this patch I get the maximum througput from my linux system
with 20MB/sec read and 15 MB/sec write (full speed 1 MB/sec both)
I also deleted the flag URB_NO_FSBR for the writeurbs, because this
makes my full speed devices significant slower.
