USB ports not working on my PC desktop

  Brian Walker 16:42 09 Oct 2018

When I plug a memory stick or SD card in to a port it does not show in Explorer. Normally it would show on the E or F drive. I've uninstalled all the USB Root drivers and then reinstalled them but still the same problem.

Hopefully you haven't blown the onboard fuse (non replaceable) do any of your sticjks have LEDs? do they light up? do external HDDs or other USb equipment work in the ports?

Yes, the sticks light up.

The only ports working are the ones for mouse and keyboards.

try USBDeview to uninstall the drives from the computer and when reconnected they should auto install and be recognised.

I downloaded and ran USBeview. It showed 4 mass storage devices. I deleted them all. Only one of the drives reinstalled and the software update for it failed.

Use Drive clean up to remove USB device drive info from the registry click here

I downloaded DriveClean UP, but there were just folders, no .exe. How are supposed to run it?

Found it but Drive Clean Up does not work with win x64 which is what I'm running.

Malfunctioning USB drives / keys

Next thing you could try is a registry hack.

a) Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.

b) When the Device Manager window opens, you need to find the USB device which is giving trouble. It may be listed under Human Interface Devices as USB Input Device.

If not there, expand Universal Serial Bus controllers. Find the one in the list for your drive, right click over this entry, pick Properties.

c) In the device properties window, change to Details tab. Click the menu for Properties and select Device Instance Path. Note down the corresponding Value it is a combination of three IDs - namely Vendor ID (VID), Product ID (PID) and Instance ID.

d) Press Windows Key + R combination, type regedit in Run dialog box and press Enter Registry Editor opens.

e) Navigate here:

HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Enum\USB(Device Instance Path)\Device Parameters

Substitute the Device Instance Path part (after USB) with the number obtained from the step c.

f) In the right pane of Device Parameters key look for the DWORD named EnhancedPowerManagementEnabled which must be showing its Value data as 1. Double click on the same to get this:

g) In the above shown box, change the Value data to 0. Click OK. Close the Registry Editor and Device Manager.

h) Reboot the PC and retry.

Thanks for your help. Before I try these options I'd like to point out that the USB port I use for my printer is working. It does not show up in Explorer but it definitely works. Does this solve anything?
