+Date: June 2012
+Contact: linux-bluetooth@vger.kernel.org
+Description:
+ The /sys/class/hidraw/hidraw*/device/oled*_img files control
+ OLED mocro displays on Intuos4 Wireless tablet. Accepted image
+ has to contain 256 bytes (64x32 px 1 bit colour). The format
+ is the same as PBM image 62x32px without header (64 bits per
+ horizontal line, 32 lines). An example of setting OLED No. 0:
+ dd bs=256 count=1 if=img_file of=[path to oled0_img]/oled0_img
+ The attribute is read only and no local copy of the image is
+ stored.
