 Tested OK.
 
 Recently I came across new app note (AN571) on SiLabs's website, describing
 the cp210x registers in detail. Attached is another minor patch with some
 further cleanups:
 
 1) Use interface no 0 (wIndex field) for all control transfers
 2) Remove reserved mask on flow control.
 
 I plan on adding GPIO support later on. Should I add this as a custom IOCTL?
 
 Thanks
