Keep KMonad running when using KVM + USB switch (device no longer exists on switching)?

[Cobertos]

I use a KVM switch with my PCs, and when I switch, all USB devices plugged in stop existing. This causes Kmonad to crash. I restart kmonad every time I switch PCs to handle this.

Is there any way to let kmonad not crash when a device stops existing? Is there any way to keep the device around outside of kmonad to prevent it from crashing? Do other people use kmonad and KVM switches?

Example log output when I switch away from the PC with kmonad on it to another PC

Repro steps:

• I started kmonad
• I clicked "NumLock" a few times to make sure it was working before I switched PCs
• I switched from source 1 to 2 on my KVM to repro
