The image is a 64x32 pixel 4-bit gray image. The + 1024 byte binary is split up into 16x 64 byte chunks. Each 64 + byte chunk encodes the image data for two consecutive lines on + the display. The low nibble of each byte contains the first + line, and the high nibble contains the second line. + When the Wacom Intuos 4 is connected over Bluetooth, the + image has to contain 256 bytes (64x32 px 1 bit colour). + The format is also scrambled, like in the USB mode, and it can + be summarized by converting:: + + 76543210 into GECA6420. + HGFEDCBA HFDB7531 + +What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_remote/unpair_remote +Date: July 2015 +Contact: linux-input@vger.kernel.org +Description: + Writing the character sequence '*' followed by a newline to + this file will delete all of the current pairings on the + device.
