Sm3255aa Memory Bar Driver 43

Expand the Universal Serial Bus controllers section. Look for a device labeled "SM3255AA" or "USB Mass Storage Device" with a warning sign.

The SM3255AA handles exFAT poorly when the allocation table grows beyond 4GB. Once corrupted, Windows triggers Driver 43 on every insertion.

Most tech-heads thought it was an urban legend. Elias had spent three years and a small fortune tracking down this single "Memory Bar."
