Hi David,
Thank you for reaching back. I am sorry that didn't work out too. Check if you have this entry in your computer's registry.
- Press Windows key + S, this will open search
- Type regedit
- Navigate to this path:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions
- Delete the keys under Restrictions of you have any.
Might as well refresh your USB root hub drivers. Here's how:
- Press Windows key + X
- Open Device Manager
- Expand Universal Serial Bus Controllers
- Uninstall all instances of USB Root Hub
- Reboot your computer.
- Check if it made a difference.
Let me know what happens.
