Well, I'm definitely not one of the brilliant people <grin> but here are a few things I would try. If the device installed any software or it it has an uninstaller you should uninstall it, then reboot. Disable any third party AV software. Then plug it in and see if it installs correctly. Also never run any of those registry fixer programs. They do more harm then good and they may install adware, toolbars, or other crap that you really don't want. Worst case they could install serious malware that steals financial information or worst of all ransomware.
if this doesn't help then try connecting it to another USB port. You can also try unplugging any other USB devices before you connect it. You could also try connecting it to another PC to see if it works. If you open device manager are there any yellow warning on any of the devices, specifically USB ports? There is a possibility that the unit is defective. Let me know if any of this helps.
