I recently purchased the ATEN 2-Port USB-C Gen 2 Sharing Switch with Power Pass-through - US3342 to share my keyboard and mouse between my Surface Laptop 4 + Surface Dock 2 and my desktop PC shortly after purchasing the Surface Dock 2.
I noticed regularly that the keyboard and mouse would drop while I was using. I would be typing on the keyboard and a given key would hold down so I typed thisssssssssssssssssssssss, then the keyboard lights would flash. The mouse also pauses from time-to-time.
Thinking it might have been the US3342 switch I contacted ATEN and am about to send it in. In the meantime I plugged a USB hub directly in and am experiencing the same issue:
TP Link UH720 USB Powered Hub with:
- Logitech c930e Webcam
- Elgato Streamdeck
- Logitech Unifying Receiver
- EPOS Impact 5066 Headset
- Filco MajesticTouch Mechanical Switch Keyboard
With the keyboard/mouse still dropping occasionally I tried disabling power management on all devices under the Universal Serial Bus Controllers section in Device Manager per this locked thread - Surface Dock keeps disconnecting/reconnecting USB devices with - Microsoft Community.
Today I plugged the keyboard and mouse directly into the dock, removing the powered hub and other devices from the equation. The problem persisted. I came across a this thread where an earlier reply suggested disabling the USB selective suspend option when plugged in. I had to use the registry route as the UI doesn't appear to exist in Windows 11 with my Surface Laptop 4. After rebooting so far it has been stable. Will see how it goes in the next few days. Hopefully don't need to go the route of disabling it across all USB devices per the following KB article - USB devices may stop functioning correctly when multiple devices connected to the same USB hub go into selective suspend (microsoft.com). Will also leave USBDeview running to see if I can spot anything.
Is anyone else making progress on this issue?
