I think I see a few problems that could be fixed, but is this reproducible?

comment:2 by diver, 5 years ago

There was another user on Telegram a few days ago with the same error.

comment:3 by diver, 5 years ago

However, this panic was on boot from usb3 for him.

comment:4 by X512, 5 years ago

I got same crash with different PC and 32 bit mode when accidently touched USB connector (why USB-A connector is so unreliable?). Only difference is MouseDevice instead of KeyboardDevice.

Crash is not 100% reproducible.

I think I know what the cause of that is, and will push a fix Sun or Mon.

Disconnecting is working better now, when disconnect and connect USB slowly, there are no crashes and mouse and keyboard are recognized again. When I tried to quickly disconnect and connect USB hub multiple times and a bit different crash appear.
