Just a quick update for DIY devices. No major functional changes but some tidying up that might be useful for people having issues with EDTracker being detected as a keyboard and/or mouse.
- Removed mouse and keyboard aspects from the USB HID descriptor
- Fixed mag scaling for MPU-9250 users
For those wondering why we haven't moved to the newer Arduino "Pluggable USB" API, we did try - but the new libraries blow the memory limit on the AVR by some considerable margin, so that's a no-go I'm afraid.
