Reverse engineering material for the HyperX Pulsefire Dart Wireless Gaming Mouse

The HyperX Pulsefire Dart Wireless Gaming Mouse enumerates at 0951:16E1 (wireless) and 0951:16E2 (wired) and uses URB_INTERRUPT for control. Messages are 64 bytes long and zero-filled.

My unit (HX-MC006B 3500457-001.B00LF) has the following firmware versions reported by the Windows software:

• Wireless firmware v4.1.0.4 (Wireless dongle firmware)
• Wired firmware v1.1.0.8 (Mouse firmware)

These values seem to be the same (each digit split by dot) as in bcdDevice USB device descriptor value.

Check firmware versions on Linux:

cat $(egrep -l '16e1|16e2' /sys/bus/usb/devices/*/idProduct | sed 's/idProduct/bcdDevice/g')

The mouse operates in "direct mode" by default. It is therefore safe to send constant changes to the mouse without wearing the on-board memory.
Settings are only saved when sending a packet starting with DE FF 00 00.

The mouse is only compatible with the newer version of HyperX NGenuity (only available for Windows 10 from the Microsoft Store) and has a different protocol compared to older HyperX mice.

The codename for the newer NGenuity software is "NGenuity2", so that could perhaps be used as the protocol name.

The reverse engineering process has been purely done by inspecting the packets sent by NGenuity Beta and the mouse itself.
Some parts of the protocol documentation have been discovered by trial and error.
No HyperX Windows software has been decompiled or inspected while creating this project.
