No driver per-seyf, but I created a couple of udev rules files that I
use. You can find them over here:
That one works with ubuntu 9.10. It goes in /etc/udev/rules.d
It isn't a driver, it just sets the permissions up properly.
Which linux OS are you using? There was some problems with certain
versions of ubuntu (Feisty Fawn and Gutsy Gibbon) where they had some
braille software which took over the serial USB ports instead of
letting the regular drivers get at them. Remove the brltty package if
you're using that version of ubuntu.
