Windows error - USB Device Not Recognized
Windows error - USB Device Not Recognized.
The "USB Device Not Recognized..." error message can appear for a variety or reasons. It is not commonly caused by a hardware fault in the drive itself. Common causes are:
- Bad USB cable.
- Insufficient power.
- Windows driver or USB problem.
The next best step is to do a series of physical tests to see if the problem can be isolated to a small component, rather than the drive itself.
- Change the USB cable with a different one.
- If the drive is bus-powered, use the USB power sharing cable. For normal drives, try using a different external power supply from a different LaCie (if possible.)
- Move the drive to a different computer.
