information log when acer-wmi initial.
Who: Lee, Chun-Yi <jlee@novell.com>
+---------------------------
+
+What: /sys/devices/platform/_UDC_/udc/_UDC_/is_dualspeed file and
+ is_dualspeed line in /sys/devices/platform/ci13xxx_*/udc/device file.
+When: 3.8
+Why: The is_dualspeed file is superseded by maximum_speed in the same
+ directory and is_dualspeed line in device file is superseded by
+ max_speed line in the same file.
+
+ The maximum_speed/max_speed specifies maximum speed supported by UDC.
+ To check if dualspeeed is supported, check if the value is >= 3.
+ Various possible speeds are defined in <linux/usb/ch9.h>.
