Error Code 43  relates to Device Manager and means 'Windows has stopped this device because it has reported problems"

When you get this error with your USB or other hardware devices, it's likely that a device driver notified the operating system that the device has failed and it was probably caused by the fact that the unit does not work over USB 3.0.

However if you have tried to connect to a USB 2.0 port and the unit is still not detected then there are a few things you can try to resolve this issue.


Restart Your Computer

If you are using a desktop computer, unplug the USB, then go to "Windows" > "Power" > "Restart".
If you are using a laptop, unplugging the USB from the computer sometimes doesn't resolve the problem because the battery still holds power. To fix this, unplug all of your USB devices, turn off the PC and take out the battery, then let the PC set for about 5 minutes.
After that, put the battery back in and restart the PC.
Next, plug your USB devices back in one at a time and make sure that they work.



Solve Error Code 43 by fixing the Device Driver

If your USB has a hardware problem or its driver or driver software is falling, you can try the following:
Update the Device Driver
Try to install the latest drivers for your USB drive. It's very likely that installing the latest drivers for the device will remove code 43 error.

Step 1. Go to "Search", type device manager, and choose "Device Manager" from the result.
Then it opens with your computer name at the top and a list of devices that are installed on your computer beneath your computer name.

Step 2. Find and right-click the problematic device and choose "Properties".
Step 3. Click "Driver" and then choose "Update Driver".
Step 4. Click "Search automatically for updated driver software".



Roll Back the USB Driver

If you have updated the device driver before the error code 43 occurred then rolling back the device driver may solve the issue.
Step 1. Open "Device Manager".
Step 2. Right-click your device driver and choose "Properties".
Step 3. Go to "Driver" > "Roll Back Driver".


Uninstall and Reinstall the Device Driver

Some users have also reported the effectiveness of reinstalling the device driver to fix error code 43 in Windows 10.
Uninstall and then reinstall your USB driver:


Step 1. Search and open "Device Manager".
Step 2. Locate the malfunctioning device in the list of devices, right-click the device, and then click Uninstall.
When a warning message appears that you are uninstalling a device from your system, click "OK". Device manager uninstalls the device.

Step 3. Right-click your computer name in Device Manager and click "Scan for hardware changes". Device manager scans your system and automatically re-installs your device.
Step 4. Right-click the device and click "Properties". On the General tab of the device Properties dialogue box, in Device status, you should see the message "This device is working properly"


Re-enable the Device

If you have tried method 2, you may be quite familiar with Device Manager now.To re-enable your USB, you just need to go to the "Driver" tab and choose "Disable Device" > "Enable Device".



Update BIOS

An outdated BIOS could also be the cause of code 43 error. Before the updating process, you should first check your current BIOS version via CMD.
If it's not up to date, go to download the BIOS update file and then update your BIOS.



Restore system to an earlier version before code 43 error was generated

Did you make any system change before receiving USB error code 43 in Windows 10?
For some reasons, making changes in Device Manager may result in code 43 issue.
To resolve the problem, use the system restore and undo recent changes related to Device Manager.
