Code 9

Windows cannot identify this hardware

What it means

The device did not report a valid hardware ID, so Windows has nothing to match a driver against.

Common causes

• A loose card or cable
• A failing device or port
• A USB port that does not deliver enough power

How to fix it

1. Unplug and reseat the device, or move a card to another slot.
2. Try another USB port, preferably on the back of the PC.
3. Check the BIOS to see whether the device is listed there.
4. If it is not listed anywhere and reseating does not help, the device is likely faulty.
