I got the idea from: http://www.linuxquestions.org/questions/linux-hardware-18/obscure-usb-serial-adapter-368278/ This patch adds the "Superial" USB-Serial converter to pl2303 so that it is detected, by the correct driver. Adds the relevant vendor:product (5372:2303) to the device tables in pl2303.c & pl2303.h. The patch has been tested against 2.6.24-22-generic.
