usb not working windows 10

[victor73]

Hi,

all my USB ports are not operable. Any device whether is memory stick or smartphone can't connect through any of the 3 USB ports.

Device manager is indicating "unknown device" and "no driver".

I have already tried:

- easy fixes like: connect / disconnect / restart laptop and or device.

- uninstall the usb root hub in Device Manager.

- using of HP assistant and HP Diagnostic tool

- updating all drivers manually from Device Manager

- restore "all defaults in BIOS"

- recovery to a previous point (unfortunately I am not sure when actually appeared this issue);

I haven't tried "Bios update" and restore to "factory state" since first one is updated and second solution will delete my files.

Thank you for any help

In the search box next to Start button type Troubleshoot. When it appears in list click it to open.

I have reinstalled Windows 10.

All USB ports are working fine.

I don't see any problem so far.

From Recovery and Reset Pc, I have used the option of keeping the old files.

Sorry I just found the KB update released by Microsoft on March 5 that fixes the usb issue:

https://support.microsoft.com/en-us/help/4090913/march5-2018kb4090913osbuild16299-251

Keep it in mind for after Windows updates again-and possibly breaks it.
