It would be great if you could dump/attach the report descriptor file. This can be found in the /sys folder structure under the USB ID for your device. ie. for my Sony Dual Shock controller -- simon@simon-virtual-machine:/sys/bus/usb/devices/1-1:1.0/0003:054C:0268.0001$ hexdump -C report_descriptor 00000000 05 01 09 04 a1 01 a1 02 85 01 75 08 95 01 15 00 |..........u.....| 00000010 26 ff 00 81 03 75 01 95 13 15 00 25 01 35 00 45 |&....u.....%.5.E| 00000020 01 05 09 19 01 29 13 81 02 75 01 95 0d 06 00 ff |.....)...u......| 00000030 81 03 15 00 26 ff 00 05 01 09 01 a1 00 75 08 95 |....&........u..| 00000040 04 35 00 46 ff 00 09 30 09 31 09 32 09 35 81 02 |.5.F...0.1.2.5..| 00000050 c0 05 01 95 13 09 01 81 02 95 0c 81 01 75 10 95 |.............u..| 00000060 04 26 ff 03 46 ff 03 09 01 81 02 c0 a1 02 85 02 |.&..F...........| 00000070 75 08 95 30 09 01 b1 02 c0 a1 02 85 ee 75 08 95 |u..0.........u..| 00000080 30 09 01 b1 02 c0 a1 02 85 ef 75 08 95 30 09 01 |0.........u..0..| 00000090 b1 02 c0 c0 |....| 00000094 -- To confirm which bits of the HID stream actually change when the pedals are pushed you could run the command as root. -- $ hexdump -v -e '17/1 "%02x " "\n"' < /dev/hidraw0 -- You'll have to change the '17' to match the actual number of bytes your wheel sends, when you get it right the columns of values will change 'nicely' as you steer/depress the pedals/etc. I'm expecting to see one column (or two adjacent if the bits don't align) change as you press the brake/etc. If you can send a small capture showing values changing for each of brake and accel that should be enough information. When we know where the data is, we can tell Linux's HID system which bits to interpret as Y and Z axis.
