Hopefully, any temporary error that might be causing this problem would’ve been fixed and all the devices should start to work. If not, proceed to the next one.
Install Windows Updates
A potential fix to the error code 43 is to update Windows to the latest version. In case you’ve disabled the automatic Windows Updates, you might be stuck on an outdated version of Windows which might not be compatible with the specific device that’s not working on Windows.
In such a case, download and install the Windows Updates to fix the issue. To get the latest version of Windows, follow these instructions:
- Go to Settings.
- Navigate to the Windows Update section and click on the Check for Updates button.
After a while, Windows will display the latest version that’s available for your computer. Install these updates and reboot the computer. If this error was caused by outdated Windows, it should be fixed after this.
Disable Power Management
If the PSU has disabled certain USB ports on the computer, the attached device would not work and the error code 43 would appear. You can disable the power management option to make sure that all the USB ports are getting the required power. To disable the power management feature, perform the following steps:
- Open Device Manager.
- Double click on Universal Serial Bus Controllers to expand it.
- Right-click on USB Root Hub and select Properties.
- Click on the Power Management tab.
- Uncheck the box for the statement: Allow the computer to turn this device to save power.
- Press Ok and reboot the computer
Change USB Selective Suspend Setting
Windows uses various methods to save energy and minimize power consumption by disabling devices that aren’t in use. Especially, USB ports that aren’t used in a while.
This, sometimes, leads to code error 43, and hopefully, by disabling these settings, the problem that’s bugging you will be fixed. To change the USB selective suspend settings, perform these steps:
- Open Settings.
- Navigate to the System section and click on Power & Sleep.
- Click on Additional Power Settings and locate the active power plan.
- Click on Change Plan Settings and a menu will appear.
- Then, click on Change Advanced Power Settings.
- Locate the USB Settings from the menu and click on it to expand.
- Now expand the USB selective suspend settings and change the status to Disable.
- Click on Apply and reboot the PC.
Plug into a Different Port
If after all the troubleshooting steps mentioned above haven’t fixed the issue for you, it could be because the port where you’ve inserted the device is faulty itself.
Try a different I/O port to make sure that it is functional. In case the front I/O panel is completely cut off or is faulty, we recommend using the I/O ports located on the backside of the computer case (on the motherboard).
Lastly, outdated BIOS could be preventing the Windows from detecting the device and the error could show up. In case you haven’t updated the BIOS in forever, we recommend doing so to fix the error code 43 along with many other underlying errors that might be a cause for concern.
