SanDisk Extreme Not Recognised In USB 3.0 Port

Saw this thread from January. My extreme 32GB was working fine yesterday. This morning it’s not recognized as a USB 3.0 device on 3 different (nearly identical) PC’s. Nothing has changed so I’m mystified. Works fine as a USB 2.0 drive.

The original poster never updated this thread, so I don’t know how – or if – he solved his problem.
