[Discuss-gnuradio] USB connectivity under gnuradio/cygwin

[CAS]

I am trying to communicate with an external board (not the usrp) 
using usb.  I have a driver installed under Windows that works fine 
with a standalone application.  I have a gnuradio block for the same 
board, but am unable to get the usb driver recognized under 
cygwin.  If someone has experience with this, I would appreciate some 
insight into whether there is something special that needs to be done 
to find the usb driver/port in cygwin to connect to the external 
board.  As an alternative can someone point me to the gnuradio code 
that handles the usb connections for other boards so that I can use 
this as a model for moving forward.

Thanks,
