[PD-dev] [comport] like object for usb?

[Hans-Christoph Steiner]

You could make something based on libusb, but USB is pretty  
complicated, so you'll want something higher level.  Perhaps these  
devices are actually USB-serial or USB-CDC (like serial).  Then they  
would not be hard to use, provided you have a driver to make them  
show up like a serial port.
