Used for measuring high-speed rotational rates (gyroscope data).
V2.2 uses a different USB PID (0xFE22 instead of 0xFE21). Fix: Update your host-side driver INF files or udev rules to recognize the new PID. Mh-fc V2.2

If you are currently running any pre-V2.2 firmware, the answer is a resounding for most applications. The combination of lower latency, better power management, enhanced security, and robust backward compatibility makes this upgrade a low-risk, high-reward decision. better power management
