For some reason, these bugs happen and I have no idea why or how to fix it.

1. Sometime after left it power off. Power back on and connect to Windows 10 PC, the Cursor update rate drops significantly. Like you play Minecraft on 10 years ago PC. (Still investigating).

2. Disconnect and reconnect, Windows (10) will report driver error "Internal error" high chance that w9013_irq is blocking BLE handler thingies.
