[Bug] Can't launch a VR iRacing session with Simhub running without it crashing 100% of the time

Describe the bug

Hey team - i just recently purchased a dayton 300 bass shaker to put under my sim rig seat and was excited to get simhub up and running to drive it. I can launch the simhub software and everything fine. And if i hit launch iRacing through it it does launch iracing. However, every time i launch a session (Test Drives if that's relevant) the second I 'enter' the vehicle, iRacing stops responding. most of the screen goes black (can see some of the iracing UI but can't shift gears or anything) and then eventually it closes. this happens 10 out of 10 times.

If i close simhub and launch a iracing session it's instantly fine.

I've tried uninstalling and reinstalling and getting the same issue. happy to share screen and show what's going on if helpful.

Hi ! This looks like usb emicor overload (when entering the game the bassshakers will get allocated and require more usb resources eventually disconnecting vr or wheel or anything Windows will decide. Can you check this guide ? https://github.com/SHWotever/SimHub/wiki/USB-Issues-Troubleshooting
