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:
A Code 43 error is generated when Device Manager stops a hardware device because the hardware reported to Windows that it's having some kind of unspecified problem.
This extremely generic message could mean there's a true hardware issue or it could simply mean that there's a driver problem that Windows isn't seeing as such but that the hardware is being affected by.
Follow the below steps to fix this issue.
1. Restart your computer if you haven't done so already.
There is always the chance that the error Code 43 you're seeing on a device was caused by some temporary problem with the hardware. If so, a restart of your computer might fix the Code 43 error.
- Note: Some users have also reported that powering off their computer completely (not just a reset) and then turning it back on has corrected their Code 43 issue, especially if it exists on a USB device. In the case of a laptop, turn it off and remove the battery, wait a few minutes, and then put the battery back in and start the computer.
2.Did you install a device or make a change in Device Manager just before the Code 43 error appeared? If so, it's possible that the change you made caused the Code 43 error.
Undo the change if you can, restart your PC, and then check again for the Code 43 error.
Depending on the changes you made, some solutions might include:
- 1.Remove or reconfigure the newly installed device.
- 2.Roll back the driver to a version prior to your update.
- 3.Use System Restore to undo recent Device Manager related changes.
3. Reinstall the drivers for the device. Uninstalling and then reinstalling the drivers for the device is a possible solution to a Code 43 error.
- Important: If a USB device is generating the Code 43 error, uninstall every device under the Universal Serial Bus controllers hardware category in Device Manager as part of the driver reinstall. This includes any USB Mass Storage Device, USB Host Controller, and USB Root Hub.
Hope this helps! Keep me posted for further assistance.
