I believe that imcokeman made a relocker that you can run from the storage card, but as I recall it wasn't recommended for general use. Try getting in touch with him or searching for things like storage card, sd card, relocker, spl, etc.

I recently had issues with my USB port as well. I wasn't able to sync, flash ROMs, etc. In my case, a simple cleaning of the port did the trick. Although yours may be actually damaged.
