You can create rules in /etc/udev/rules.d eg "10-local.rules (see man udev) and do something like: BUS=="usb", SYSFS{serial}=="1234",KERNEL=="ttyUSB*", SYMLINK+="wx" this way whenever the USB device is plugged in a symlink will be created from /dev/wx pointing to /dev/ttyUSBx The only problem is many of the cheap usb to serial adapters all have a serial number of "0" and there is nothing unique separating one device from the other.
