4GB Cruzer Mini shows up as M-Sys Pan UCL mode USB Device on Device Manager in Win XP

My 4GB Cruzer Mini seems to be corrupted.

It shows up as M-Sys Pan UCL mode USB Device on Device Manager in Win XP.

I have another 1GB Cruzer Mini which shows up OK on the same PC.

Uninstalling and Scanning for new hardware changes does not help.
