Option # 1: Remove device drivers

If you find yourself in trouble when you connect a new device, then the problem is probably the incompatibility of the driver from the new device with the old one. In such cases, it is necessary to remove the hardware driver for the system to deliver new software from the connected device. For this:

• Start-> right-click on “My Computer” (in versions of windows above 7 – “This computer”), in the pop-up menu, select “Properties”.
• A window with the name “System” will open in front of you.
• In the window on the left, look for the Device Manager and click on it.
• In the dispatcher that appears, we are looking for the device with which the system is having problems.
• We click RMB on your equipment and click “delete device”.
• We confirm our intentions, restart the PC.
• Connect your device.

Option number 2: Checking the USB port for serviceability

There are times when, due to external influences on the ports, they fail completely or work with errors. Therefore, before you commit a sin on the software component, make sure that the port is working. For this:

• Examine the “socket” carefully for damage or foreign objects.
• Plug your device into other USB connectors and see how the system reacts. If Code 43 does not disappear when plugging the device into other jacks, go to the method described below. (But it is worth remembering that if the south bridge fails on the motherboard, absolutely all USB connectors may not work, therefore, if the system does not detect the connected device and there are no errors, this is a reason to contact the PC repair masters).

Option number 3: Disable energy saving

In the windows system, you can control the power supply of the connected equipment. It happens that the OS turns off our device to save energy, after which an annoying error with code 43 appears. To check if our device is turned off by the system, you must:

• Go to start-> PCM on “This Computer” -> properties.
• In the window that appears with the name “System”, on the left we are looking for Device Manager.
• We find our connected equipment and click on it with RMB -> Properties.
• In the pop-up window, select the “power management” section.
• We find the parameter that allows the equipment to be turned off in order to save energy, and uncheck it.
• We confirm our actions.

• A window will appear prompting you to save a backup copy of all deleted records -> agree to save.
• We repeat steps 1-3, restart the computer.

Option # 5: Restore system files

The proposed method refers to ineffective methods, but it’s worth a try.

• Run the command line with administrator rights (start-> write “cmd” in the search bar -> click on the icon that appears cmd-> run as administrator).
• We type in the pop-up black window sfc / scannow.
• We are waiting for the end of the check.
• Reboot pc.

Option # 6: Is the device itself malfunctioning?

It is possible that the device itself that you want to connect begins to malfunction, thus the system gives an error. Try turning off your PC, turning off your equipment, and waiting a couple of minutes. If this does not help, check the connected device on other computers with windows 7, 8, 10, and if the equipment behaves the same way or is not recognized, then the problem may lie in the device’s USB controller.
