USB-C port disappeared from device manager [HP ENVY x360 laptop]

[packman3]

Hi,

I use my USB-C port for connecting to a second monitor via the HP USB-C to HDMI 2.0 connector. This was working fine for weeks until yesterday. I got a code 10 error on the USB-C port in device manager. 

So I googled the problem and there were suggestions that solving a code 10 could be done by uninstalling the driver and restarting the machine. So I did that but now device manager does not even show the USB-C port and the laptop does not detect a change when I disconnect and reconnect the adapter from the USB-C port. 

I'd be grateful for suggestions on how to get it back in device manager. 

Things I've tried: 

- updating the HP BIOS 

- shutdown and hold power button for 30 seconds

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Let's try Microsoft system restore: System Restore returns your computer to the files and settings from the restore point. Your personal files and documents are not affected.

1. Save any open files and close all open programs.
2. In Windows, search for restore, and then open Create a restore point from the results list.

System Properties opens with the System Protection tab selected.

• On the System Protection tab, click System Restore.

The System Restore window opens.

1. Click Next.
2. Click the Restore Point that you want to use, then click Next.

The confirmation window opens.

1. Click Finish to restore your computer to a previous point.
2. Do not interrupt System Restore when it starts. This can corrupt your hard drive and create more problems. Click Yes in the warning that appears.
3. System Restore returns the computer configuration to a previous point in time and restarts.

Hope this helps! Keep me posted for further assistance.
