Works in ML | Knoppix | MS-WIN , drivers are available for Linux + Windows.

Knoppix is (Debian-Based) , you have to add a couple of lines to /etc/init.d/bootmisc.sh to
load drivers at boot-up ! All other Linux - Win there is no hitch!
(INSTRUCTIONS - in Install tell what lines to add to bootmisc.sh)

I'm using one now on Knoppix, connect at 50666 most of the time.

Connect in Windows is 46666 most of the time.
