-                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
