USB port is not working after BIOS update

HP Recommended
HP Spectre x360 Convertible 13-ap0xxx
Microsoft Windows 10 (64-bit)

Hi!

I have a HP Spectre x360 notebook for around six months, and I used it connected to a monitor via an USB-c - HDMI adapter. However after the latest BIOS update, it seems that my USB port is not working, it doesn't recognize the adapter, but I can charge the laptop by it. However via the other USB-c port I can connect my adapter (Windows is recognizing it) but it's not working with the HDMI cable.

 

I checked the Device Manager, and I can only see two USB roots there (my laptop has two USB-c ports and one USB-A, it means I should have seen three roots, right?). I tried to uninstall the roots in DM, tried to change the Power Management settings, but it didn't work. 

 

Can you please provide some help with this issue? 

 

Thank you in advance.

@cseri_balazs,

 

Thank you for posting your query on HP Community,

 

Have you tried to connect using different USB Devices?

Have you tried to use a different cable and check?

 

Please try the steps recommended below.

 

Update the device driver through Windows Update by doing the following:

Click Start
Select Settings
Click Updates & Security
Click Windows Update 
In the Windows Update settings window, click Check for Updates, and install all updates listed.

 
1. Open Device Manager.
2. Expand category “Universal Serial Bus controllers”.
3. Double-click the “USB Root Hub” device, and click the Power Management tab. (if there’s more than one USB Root Hub device, repeat these steps for each one.)
4. Turn off the Allow the computer to turn off this device to save power option, and click  OK button.


Disconnect all USB devices connected to the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.
In Windows, search for and open Device Manager.
The Device Manager window opens.
Double-click Universal Serial Bus Controllers to expand the list.
Right-click the first USB Root Hub in the list, then select Uninstall.
Click OK to confirm.
Continue uninstalling all USB Root Hubs listed.
Close Device Manager and restart the computer.
If the USB device that is having problems came with software and it was not previously installed, install the software now, following the manufacturer instructions.
Reconnect the USB device that was having problems and test it to see if it works.

 
Open Device Manager (Right Click on Windows Logo and Click Device Manager).
Now find and expand Universal Serial Bus controllers. Now right click on USB drivers and click Uninstall. Do for all USB drivers one by one.
Now Restart your PC. The USB drivers are automatically re-install and solve the corrupted USB devices.
Right-click on the battery icon and click Power Options.
Click Change plan settings.
Now click Change advanced power settings.
Find and expand USB settings.
Expand USB selective suspend settings and Disable both On battery and Plugged in settings.

 

Try updating BIOS and chipset drivers on your PC using HP support assistant and check if it helps.
