Usb Device Id Vid 058f Pid 1234 Full !new! Jun 2026

The underlying NAND flash memory chip has physically degraded past its read/write limitations.

To avoid encountering the 058f:1234 identifier in the future:

: Rather than indicating a specific consumer brand (like Kingston or SanDisk), the 1234 string is a sequential placeholder code. It usually signals that the controller chip is running on an unconfigured, default factory firmware, or that its customized partition parameters have been erased.

If you want to proceed with fixing your drive, let me know the or Flash ID (FID) code provided by a tool like ChipGenius or Flash Drive Information Extractor. I can help you identify the exact version of the Alcor MPTool required for the repair. Share public link

The VID 058F PID 1234 identifier is a USB device signature that serves as a starting point for diagnosis rather than an end state. When encountered, it indicates that a device—most likely an Alcor Micro-based USB flash drive—has reverted to a generic identification mode, typically due to firmware corruption, failed operations, or physical wear. The underlying NAND flash memory chip has physically

The internal software microcode on the controller chip is corrupted due to sudden power loss or improper removal.

If your chip is an older or AU6988 , look for AlcorMP packages from the corresponding launch era.

If your device with PID 1234 is not recognized on screen, navigate to the tool's folder, open the AlcorMP.ini configuration file, and verify that the VID and PID parameters match 058F and 1234 . Alternatively, utilize the standalone tool to temporarily reset the identifier back to factory standards ( 058F / 6387 ).

Upon enumeration, a device with VID 058F PID 1234 typically identifies itself as a device, though it can also appear as a vendor-specific class. As an MSC device, it emulates a block storage device (like a hard drive or SD card reader). The Alcor controller integrates a microcontroller that handles the translation between the USB protocol and the underlying NAND flash memory or removable media.
