Usb Device Id Vid 058f Pid 1234 !link! Full
In the case of flash drives, this controller manages wear leveling, error correction, and bad block management. However, Alcor controllers with this PID are often found in —for instance, a USB drive that contains both a public partition and a secured, encrypted partition accessible only via a vendor-provided utility. The PID 1234 may indicate the base firmware configuration without encryption, or a "bridge" mode awaiting firmware update.
