USB devices freeze occasionally when scrcp is running

Hi.

I discovered scrcpy just today, and it's really great and almost flawless so far!
The only thing I found to be annoying is that, when scrcpy is up¹, my USB devices(?) seem to die every now and then. Most noticibly, I had to unplug and re-plug my mouse and keyboard for over 10 times today as they just froze (usually at the same time) and kept spamming inputs.

**Where it occured:** Two unrelated Windows 10 (1809) computers.

For this to happen it doesn't even matter whether I'm operating inside the scrcpy window or not. scrcpy just has to be running in the background.

If there's anything I can send in for further investigation (like debug logs or some sort of USB crash dumps?), let me know.

¹it happened today for the first time and on two different computers, so it's gotta be scrcpy

Reproduce the USB freezes on the two reported Windows 10 setups while scrcpy runs in the background, then collect the debug logs or USB crash dumps requested in the issue. Done means identifying whether scrcpy triggers the freezes and confirming that the issue no longer occurs or is properly characterized.
