ok, I'm not at all familiar with kernel development but here's my 
contribution.
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.
