LOL... Yes this driver truly does suck. I started with a copy that came
with the device (well, downloaded it from their web site). I did the
bare minimum to get it working with the latest kernel, in the hope that
I can get others to help make it into a proper driver.

grumble, this is a bit more work than I currently have time for. This
driver needs some major loving. But my heart is someplace else, and
until I can get a divorce from what I'm currently working on, this
driver will need to find lovers from someone else.
