vrf Can the M series of libraries communicate with a generic USB device?

Question asked by papineni_vinod on Jul 2, 2004
The IO Libraries come into the picture when it is USB to "something"
converter, where the something is a port supported by IO libraries
(example: GPIB, RS232, LAN). Otherwise VEE would talk to the device
directly, using a dll/ActiveX?
