Problem

Dino-Lite does not turn on and device manager reports error Code 43.

Solution

Connect the Dino-Lite to a different USB port.
If it is a desktop computer, try a port on a different part of the computer, such as front vs back.
Make sure the Dino-Lite is connected directly to the PC and not through a USB hub or extension.

If the steps above do not resolve the issue

Use the following steps to uninstall and reinstall the device.

1. Connect the Dino-Lite via USB
   
2. Right-click on Computer, My Computer, or This PC on your desktop or start menu, then select Manage
   
3. In the computer management window, select Device Manager
   
4. In the Device Manager window, open the Imaging Devices category, or, if that category is not visible, open the Other Devices category.
   
5. Under the selected category, right-click on the Dino-Lite and select Uninstall. If there is a checkbox option to “Delete the driver software for this device”, ignore it and leave the box unchecked, and click OK
   
6. From the top of the Device Manager window select Action then click Scan for hardware changes
   
7. After about 15 seconds, the Dino-Lite should reappear under the Imaging Devices category without any error sign. If there is still an error, proceed to the next set of steps.
