Before using any tool, you need to know the exact chip model. VID/PID only tells you it's an Alcor Micro. You might need to open the casing to look at the controller chip or use a tool like ChipGenius to find the (e.g., AU6986, AU6987, SC708). Step 2: Use Alcor Micro Flash Tools
When the Product ID flips to , it indicates that the firmware has failed, the controller cannot talk to the NAND flash memory, or the drive has been masked by generic placeholder values due to data corruption. This guide details the causes of this issue and provides step-by-step instructions for recovery. Technical Breakdown: What VID 058F PID 1234 Means
The USB\VID_058F&PID_1234 device identifier indicates an Alcor Micro-based device. While often associated with cheaper, generic, or fake drives, these devices can usually be repaired using low-level formatting tools. By identifying the specific controller chip and using the correct Alcor MP Tool, you can restore functionality to the drive. usb device id vid 058f pid 1234 full
: The device might be listed as a "Generic Mass Storage Device" but fails to open in File Explorer. How to Fix a Corrupted Alcor Drive
No. The built‑in mass storage driver in Windows, macOS, or Linux is sufficient for normal operation. Only install manufacturer drivers if you need advanced functionality like hardware encryption or card reader modes. Before using any tool, you need to know the exact chip model
If you are seeing this ID in your system logs but the device is not working, the issue is usually not the ID itself, but rather:
Because "PID 1234" is generic, you need to know which Alcor chip is inside (e.g., AU6989, AU6986) to find the right repair tool. Fixing a fake USB flash drive – Roo's View - Lowtek.ca Step 2: Use Alcor Micro Flash Tools When
The program should detect the flash drive in one of the slots, even if Windows cannot read it.
: If your device is a flash drive but shows this VID/PID, it is likely a fake capacity drive or a device with corrupted firmware.
Before attempting to flash or repair the device, determine exactly what physical hardware you are working with. Use USB Hardware Identifiers
Modifying VID/PID with tools like AlcorMP can cause driver conflicts and make the device unrecognizable. Only advanced users should attempt this, and always keep a backup of the original firmware.
