+               The /sys/class/hidraw/hidraw*/device/speed file controls
+               reporting speed of wacom bluetooth tablet. Reading from
+               this file returns 1 if tablet reports in high speed mode
+               or 0 otherwise. Writing to this file one of these values
+               switches reporting speed.
