Is there some way to get the USB ID of a serial port through pyserial on Linux and/or Windows? USB serial port devices have device names determined by when they were plugged in. So, if you have more than one USB serial device, you need the USB device's built-in ID to figure out what's out there.
Is there a way to get that info portably? John Nagle -- http://mail.python.org/mailman/listinfo/python-list
