3] Manually install the missing driver files

This error could be a result of missing driver files. Hence, if the scenario is applicable, you can manually install the missing driver files and then check if the error is fixed.

First of all, you need another computer without this error. So, go to another computer and move to the following location:

 C:\Windows\INF

Now, locate the mdmcpq.inf file and copy and paste it to an external drive. After that, move to the below location:

C:\Windows\System32\drivers

From the above location, copy the usbser.sys file to the same external drive that you used previously.

Next, connect the external drive to the problematic computer and copy both files to their respective locations. Copy and paste the mdmcpq.inf to C:\Windows\INF and the usbser.sys file to C:\Windows\System32\drivers.

You can now reconnect your device and check if the error is resolved.

Another way to install a missing driver file to fix this error is as follows:

First, disconnect your USB device and move to the C:\Windows\INF location in your File Explorer. Now, right-click on the wpdmtp.inf file and choose the Install option from the appeared context menu.
