Unifying Support

Introduction

This plugin can flash the firmware on Logitech Unifying dongles, both the Nordic (U0007) device and the Texas Instruments (U0008) version.

This plugin will not work with the different "Nano" dongle (U0010) as it does not use the Unifying protocol.

Some bootloader protocol infomation was taken from the Mousejack[1] project, specifically logitech-usb-restore.py and unifying.py. Other documentation was supplied by Logitech.

Additional constants were taken from the Solaar[2] project.

GUID Generation

These devices use the standard USB DeviceInstanceId values when in DFU mode:

  • USB\VID_046D&PID_AAAA&REV_0001
  • USB\VID_046D&PID_AAAA
  • USB\VID_046D

When in runtime mode, the HID raw DeviceInstanceId values are used:

  • HIDRAW\VEN_046D&DEV_C52B
  • HIDRAW\VEN_046D

Design Notes

When a dongle is detected in bootloader mode we detach the hidraw driver from the kernel and use raw control transfers. This ensures that we don't accidentally corrupt the uploading firmware. For application firmware we use hidraw which means the hardware keeps working while probing, and also allows us to detect paired devices.
