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:
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).
Update BIOS
Lastly, outdated BIOS could be preventing the Windows from detecting the device and the error could show up.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.
