Description: When read, this file returns the driver version.

The format of the string is "v<major>.<minor>.<patchlevel>".

This attribute is used by the userland tools to find the sysfs-

paths of installed kone-mice and determine the capabilites of
|

the driver. Versions of this driver for old kernels replace
|

usbhid instead of generic-usb. The way to scan for this file

has been chosen to provide a consistent way for all supported

kernel versions.
