Attached are drivers for the KB Gear JamStudio Tablet. There are two
files, one is against 2.4.20, the other against 2.5.62. I'm hoping this
isn't too late in the 2.4.21-pre stages to get included (or the 2.5, for
that matter =). This driver Works For Me, on both 2.4.20 and 2.5.62.
Anyway, as usual, comments, complaints, and patches are more than
welcome.
