The device doesn't show up in /dev/input. Older kernels work fine. That is because the new hid-logitech-dj driver claims the device. The device arrival notification appears: 20 00 41 02 00 00 00 00 00 00 00 00 00 00 00 and we read the report_types bitfield (02 00 00 00) to find out what kind of device it is. Unfortunately the driver only reads the first 8 bits and treats that value as a 32-bit little-endian number, so on a powerpc the report type seems to be 0x02000000 and is not recognized. Even on little-endian machines, connecting a media center remote control (report type 00 01 00 00) with this driver loaded would presumably fail for the same reason. Fix both problems by using get_unaligned_le32() to read all four bytes, which is a little clearer anyway. After this change, the wireless mouse works on Hugo's PowerBook again.

Reporting speed for both tablets can be changed by somethinkg like: echo 1 > /sys/class/bluetooth/hci0/hci0:1/{device No}/speed Accepted values: 0 - low speed, 1 - high speed. The way of changing reporting speed is the same for Graphire and Intuos4 WL.
