Hi Octopusenvy
The model VPCSB1C5E is a non-US model thus we have no information on this unit. I understand that you already searched everywhere but failed to find the driver. Have you tried reformating the unit back to factory setting? If you can't do a system restore then you might want to consider reformatting the unit. Make sure to back up all your files first before you start the procedure. If that didn't work, we highly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/ to assist you with this issue.
Regards,
Jen
