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.
