Hey I'm writing to the mailing list because I fear that
https://sourceforge.net/projects/aiptektablet/ is dead (last update
I have to Aiptek Hyperpen mini devices which are identical to the
point except for the bcdDevice id.
The first one with the id 1.01 works but the other one with the id
1.02 doesn't work so well.
The points are mapped correctly but sometimes the stylus stops working
completly (seems to be the case if the pressure is too big or the
angle of the stylus is changed).
On Windows the device works flawless.
I attach the lsusb output with the hope that someone can help me.
with kind regards,
