[Xastir] usb->serial adapters?

Make sure it has an FTDI chipset in it.  FTDI devices have a unique
serial number so that the port is uniquely identifiable no matter
where it is plugged in to the USB tree.

When you're setting up don't use /dev/ttyUSB3, use

/dev/serial/by-id/usb-FTDI_USB_Fast_Serial_Adapter_FTTOYUBC-if00-port0

Which is both unique and repeatable - no matter where you plug the
device in, it will show up with this name (FTTOYUBC is the serial
number of this particular chip).


I've purchased a 16 port rack mount version from this outfit at work:

I've got one of these at home:

but a pretty obvious downside is that it's a bare board, no enclosure.
