Can I stop USB devices from disconnecting when using KVM switch?

I guess this is KVM switch specific. Some KVM switches emulate virtual keyboard, mouse and monitor for each computer it is connected to whereas some just switch away the connection without further processing. As all of us can guess, the switching type is much cheaper...

Not too much we can do here I believe...

This worked for me:

1. Device Manager > USB Root Hub > Properties > Power Management (tab)
2. Uncheck Allow computer to turn off this device to save power.
3. You can apply this to other devices under Device Manager > Universal Serial Bus Controllers
4. You may need to restart computer for this to take effect.

For me, the effect was not immediate, but after 1 week or so, the switch speed has increased dramatically (2-4sec).

Sometimes, I still wait like 13sec, but after restart or unplug, everything works fast again.

Best regards!
