Problem: an unbranded USB-serial converter is not detected
Steps taken to resolve the problem: (unsuccessful) force usb-serial detection by adding (Debian?) udev rules -
detects device but incorrectly defaults to generic which doesn't work
(successful) added vendor:product to pl2303 / recompile / insert module

Can you send me the patch that you made, in the format described in
Documentation/SubmittingPatches, through email, and I will be able to
apply it and give you the proper credit.


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.
