After plugging in the device. Go to device manager (In run type "devmgmt.msc") In Device manager go to "Universal serial bus controllers" It should list the storage devices that you have connected to your PC. Right click and then click "Uninstall. Remove the USB drive and restart your system.
Try connecting the device again, I think this should solve the problem.

first you need to go to Device Manager by double-clicking on the System icon in Control Panel, choosing the Hardware tab, and clicking Device Manager.
