Identify printers by UUID
Apologies if this has been discussed previously. It would be really handy for me if Repetier server queried and recognized printers by something other than the serial port. Whichever printer I turn on first becomes /dev/TTYusb0. This may or may not match the printer that was last turned on first. I have two (soon to be three) printers running off of my Repetier server installation, and it would be really helpful to me if I could set a UUID in the firmware (Marlin supports this) and have the server recognize the UUID.
