its possible if the udev rules are old or the kernel is a little old
it will  not autodetect, Most USB/serial are the same chipset (A
Prolific one) and the usbserial driver will work but you may need to
modprobe usbserial VENDOR=0x0000 DEVICE=0x0000 where there 0x000 are
the appropriate numbers discovered by lsusb.
