    Hi

    Win 10

    My USB port is not seen and an article I found said to delete the Universal Serial Bus controllers. My question is, how do I select for more than one to delete? Or must I do them one by one?

    Thanks, Mark

      If you’re using a desktop PC and/or a USB keyboard, removing the USB controllers will disable the keyboard and mouse, so you’ll need to have another way to control it; such as a PS/2 keyboard or an RDP or VNC connection from another system.

      You’ll need to do them one by one, but removing the host controller will remove everything attached to it. There’s normally only a handful of them.

        If you are going to delete your USB devices, be very careful when depending on a PS/2 keyboard and mouse. Most of the PS/2 adapters are actually USB adapters which convert from USB to PS/2. Therefore, if you delete USB, PS/2 will quit working, and you will no longer have a keyboard or mouse.

        I would advise against deleting any USB devices, unless they have a yellow error symbol next to them. Even in that case, BE CAREFUL! You don’t want to make your computer unusable.

        Here is a discussion that I had on Windows Secrets a long time ago about USB going down in my computer and what I had to do to get a working keyboard and mouse:

          Only works if you have a physical PS/2 port. A PS/2 keyboard in a USB adapter is no different than a real USB keyboard.

      USBDeview is a useful utility for viewing current and past USB Devices.

      Use caution when using this software as devices currently in use can be removed by you including your keyboard, mouse, and printers. However — at least in my case — keyboard, mouse, and printer-related devices are clearly labelled.

      I wholeheartedly agree with @geekdom… Nir Sofer’s small, free, portable USBDeview is the way to go for ease of use.

      1.. Download, unblock and unzip USBDeview.

      2. *Right*-click on the USBDeview.exe file and use Run as administrator from the context menu. (You’ll need elevated rights to remove USB port entries from the registry.)

      3. Sort the list by clicking on the header of the Connected column. Don’t touch anything that shows as connected otherwise you will temporarily disable your mouse and keyboard… and the USB ports they are connected to.

      4. You can use multi-select to choose disconnected ports and devices (shown with a white roundel in the first column) then, from the File menu, select Uninstall Selected Devices.

      usbdeview_uninstall_selected_devices

      It’s quite safe. All it does is remove registry entries… and these will automatically repopulate when the port or device is next used again.

      5. Close USBDeview and reboot your device.

      Post back whether this resolves your USB controller issues.

      Hope this helps…

      Thanx everyone. It turned out to be a intermittent USB socket connection. I will get the USBDeview for the future.
