I want to communicate with a serial device over the USB that is not a 
recognized device.  It is a PLC(programmable logic controller). How do I 
tell which USB device file to open?  i.e.; /dev/bus/usb/002/001 or 
002... .  Is there a way to tell what I'm plugged into?  Is there a USB 
howto for programmers?
