#24 KYE EasyPen M406 driver needs to be implemented

[Nikolai Kondrashov]

A KYE EasyPen M406 diagnostics was obtained and a kernel driver needs to be implemented.

The diagnostic dumps are available in the devices repo: http://digimend.git.sourceforge.net/git/gitweb.cgi?p=digimend/devices.git;a=tree;f=KYE_EasyPen_M406

However, the way frame controls are reported is incompatible with the HID standard: the mode doesn't affect the way the wheel rotation is reported, but is just reported with a separate report ID. This requires creating a synthetic input device aggregating both wheel mode and rotation reports.

A compromise would be to first implement a driver supporting pen only.
