Hanvon tablet driver Hanvon tablet driver
==================== ====================
Linux kernel driver for some Hanvon tablet usb models. Following functionality Driver for Linux kernels which supports complete functionality of the tablet:

Revision history Diagnostics
================ ===========
0.0.1 - initial release After insmod, check with dmesg, if the module was loaded properly.
0.2 - corrected pressure detection, working slider button "USB Hanvon tablet driver" should appear in the listing.
0.3 - remaining buttons also working, added x and y tilting
0.3b - patch for AM1209 from Markus Zucker applied lsmod should also contain hanvon in its listing: lsmod | grep hanvon
0.3c - patch for AM1107 from Daniel Koch applied
0.3d - support for right side buttons of AM1107 and AM1209
0.4 - code cleanup, RL0604 patch from Daniel Clemmer
0.5 - code cleanup, AM0605 support
