USB xHCI Compliant Host Controller Error Code 10

HP ENVY x360 m6 Convertible
Microsoft Windows 10 (64-bit)


I am having a problem with my USB ports. Simply, they doesn't work any more because Windows can't start the device.  When I open the device manager I get this message:


This device cannot start. (Code 10)

{Operation Failed}

The requested operation was unsuccessful.




These are the solutions I have tried:

1. Updating the driver

2. Uninstall/reinstall

3. System restore point

4. Manually updating the driver by browsing for files

5. Scanning for hardware changes

6. Updating windows (already checked for updates and all good)

7. Clean Windows installation

8. BIOS update

     - Version: F.58

     - Vendor: Insyde

9. HP support assistant update (all up to date). Through HP PC Hardware Diagnostics UEFI

10. Updates from Intel driver & support assistant (all up to date)



  • Windows 10 Pro Version 1909
  • OS build: 18363.476
  • Product number: W2K45UA#ABA


I have checked USB ports with HP PC Hardware Diagnostics UEFI and I got the below error




Trying to solve this issue for 3 weeks now.


Thanks in advance for your help.

@Khaled-Saad That's quite a detailed description of the concern and the steps you've performed so far, I appreciate that, also, I have managed to decipher the error code you've mentioned, it seems to be a hardware malfunction, here's what it represents:

Failure ID (you had mentioned) = 6C3XV9-8A39SJ-GXGK7F-8D0J03

Deciphered to = Code 434

Represents error = USB Failure


And I suggest you talk to HP support and discuss your options, follow the below steps to get started:


1) Click on this link -

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!


Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
