The Code 43 error is one of several Device Manager error codes. It is an error message that occurs when Device Manager has stopped a hardware device .
This generic message may mean that there is a real hardware problem, or it may simply mean that there is a driver error that Windows cannot identify but the hardware is affected by it.

- Restart your computer if you haven’t already , there is always a chance that error Code 43 is caused by some temporary hardware issue. If so, restarting your computer may fix the Code 43 error.
- Plug the device into a different computer and then properly eject from there. Plug it back into your computer to see if that fixes the Code 43 error.
- Did you install a device or make a change in Device Manager just before you got the Code 43 error message? If so, it’s possible that the change you made caused the Code 43 error. If you can, undo the change, restart your computer, and then check again for the Code 43 error.
Depending on the changes you make, some solutions might include:
