Windows 10: USB ports being deliberately disconnected or disabled?
USB ports being deliberately disconnected or disabled?
I am being bugged by a problem associated with USB ports apparently being intermittently disabled or disconnected.
The result is a cacophony of device disconnected sounds being played. It ultimately means the PC has to be shutdown. Occasionally a device connected sound will be heard as well.
I have heard that Win 10 is disabling or disconnecting USB ports to save power for tablets and such. Understandable for limited power availability but for PCs where power is always available this seems misguided.
I need to know if this is by design or can it be selected off via registry option.
I had the same problem, it was caused by an Alfa Wi-Fi adapter that didn't like being on a 10m active USB cable.

Have you checked your power plan Options? you'll find a link to Change Advanced Power setting. There you will find USB Settings. There you can select USB Selective Suspend setting. Mine is set to disable and I have no issue with disconnects
Thank you very much for the pointer.
I have changed mine to Disabled and wait to see if it is the correct thing.
