-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.
