USB C port only works one way up charging and doesn't work at all for display or other functions

[LeuvenRich]

My USB C port in the corner of my latop is only partially functional. It works for charging but only if the USB cable is one way up (not the other way). It also doesn't seem to function for anything else. I've tried the suggestions in this post and I haven't been successful.

I couldn't get the UEFI tool to test USB ports. Does this functionality exist in the tool (under which category is it?)

Update - I put a USB hub in the affected port and got this error message. I don't get this error message putting in the unaffected port.

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing USB C port issue with the HP Spectre X360 Convertible Laptop PC.

"USB device not recognized" is an error that usually occurs on Windows computers when you plug in a USB device

I have a few recommendations 

• Update your Notebook computer to the latest BIOS from HP.COM.
• Make sure the Windows and HP support assistant updates are up to date. 
• Unplug Your Computer from the Power Source

• Change the USB Port

• Uninstall USB Device Driver to Make USB Recognizable

Change the USB Selective Suspend Settings

Another possible reason your USB malfunctions is that the hub driver suspends the USB automatically. In this case, changing the USB selective suspend settings could help.

Step 1. Right-click on the Windows icon and click Power Options.

Step 2. In the Choose or customize a power plan window, click Change plan setting.

Step 3. In the Edit Plan Settings window, click Change advanced power settings.

Step 4. In the Power Options window, find and expand USB settings, expand USB selective suspend settings, and Disable both On battery and Plugged in settings.

Step 5. Click Apply and then OK to save the settings.

Fix USB Root Hub

The USB root hub is the software driver that lets you connect multiple USB peripherals to your computer. Most computers have multiple root hubs so you can share the data bus across multiple devices. So, if the computer cannot recognize your USB drive, try to fix the USB root hub.

Step 1. Open Device Manager, find the Universal Serial Bus controllers option and single-click it to expand it.

Step 2. Find the USB Root Hub option in this category, right-click it, and choose Properties.

Step 3. Go to the Power Management tab and uncheck the "Allow the computer to turn off this device to save power" option. Then, click OK to save your changes.

Hope this helps! Keep me posted.
