My flash drive worked fine until I updated the software. Now it gives the message "USB device not recognized" on my desktops and laptops.. I have recently discovered that the drive will work on an older machine with USB 1.0. Is there a way to replace the software to get the drive working on 2.0 again?

My U3 Cruzer 160GB has an identical problem. It works fine on one XP system, and doesn't on another. Both of with SP3.
Looking into Device Manager, I see the notorious "Unknown Device". Tried 5 different USB ports.
Any solution from SanDisk?
