Understanding the USB Device VID 058F PID 1234 If you have discovered the identifier VID 058F PID 1234 in your Device Manager, you are likely looking at a generic USB flash drive built with an Alcor Micro Corp. controller. This specific combination is one of the most common signatures for mass-produced, "no-name" thumb drives and is frequently associated with firmware issues like the "No Media" or "0 MB Capacity" errors. What is VID 058F PID 1234?

Every USB device has a Vendor ID (VID) and a Product ID (PID) to help the operating system identify it.

Vendor ID (058F): Assigned to Alcor Micro Corp., a major manufacturer of USB controller chips.

Product ID (1234): A generic product ID often used by Alcor Micro for mass storage devices or flash drives. usb device id vid 058f pid 1234 full

This ID often appears when a drive is in a "test" or "generic" state, or when the firmware has become corrupted, causing the computer to see the controller chip but not the actual memory storage. Common Issues and Symptoms Devices with this ID often exhibit the following problems:

"No Media" Error: The drive is detected as a letter (e.g., G:) but shows "0 bytes" of space and cannot be opened.

Write Protection: You can see your files but cannot delete or add new ones.

Generic Name: The device appears as "Generic USB Flash Disk" or "USB Mass Storage Device" rather than a brand name like Kingston or SanDisk. How to Fix a Malfunctioning VID 058F PID 1234 Drive

If your drive is showing "0 MB" or "No Media," standard formatting usually won't work. You likely need a Production Tool (MPTool) specifically designed for Alcor Micro controllers. Before diving into specifics, it is crucial to

Identify the Controller: Use a tool like ChipGenius to find the specific "Controller Part-Number" (e.g., AU6989SN, AU6986).

Download the MPTool: Search for the Alcor Micro "MPTool" or "AlcorMP" version that matches your controller number on specialized sites like USBDev.ru or FlashBoot.ru.

Reflash the Firmware: Run the tool to "Low-Level Format" or reflash the drive. Warning: This will permanently erase all data on the device. Quick Troubleshooting Tips

Before attempting a high-risk firmware flash, try these standard Windows fixes:

Standard USB Identifiers - Windows drivers - Microsoft Learn Thus, VID 058F PID 1234 means: An Alcor Micro Corp

If your operating system fails to recognize the device despite seeing the VID/PID, one or more of these issues is present:

The combination of Vendor ID (VID) 058F and Product ID (PID) 1234 identifies a specific class of USB hardware. Based on the USB Implementers Forum (USB-IF) assigned identifiers, this entry corresponds to hardware manufactured by Alcor Micro Corp.

If after all driver reinstalls, OS switches, and configuration tweaks the device still shows errors with 058F:1234, consider hardware failure:

If software fixes don’t help, consider hardware:
