Hi Shane,
- Which operating system are you using?
2. Have you made any recent changes to your computer?
If you use Windows 7, follow the below steps and check.
**Method 1:**Run the hardware and devices troubleshooter.
Refer to the following link:
http://windows.microsoft.com/en-IN/windows7/Open-the-Hardware-and-Devices-troubleshooter
Method 2: If the above step does not help us to diagnose the issue, uninstall the drivers for USB [Universal Serial bus] host controller and restart the computer. Let Windows install the generic drivers and then see if it helps you to fix the issue.
a) Open Device Manager by clicking the Start button, then Device Manager in the search box.
b) If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
c) Look for the device under USB [Universal Serial bus] host controller, right click on it and select Uninstall.
d) Reboot the computer.
e) On reboot, Windows 7 should re-install the drivers automatically.
If the issue still persists, I would suggest you to contact Intenso support.
