The USB device ID VID 058F PID 1234 full identifier points to an Alcor Micro USB 2.0 hub or card reader. It is not malicious, and in most cases, the lack of a driver is the primary obstacle. By installing the correct chipset or card reader driver from your laptop manufacturer, using Windows Optional Updates, or manually forcing a generic USB hub driver, you can resolve the error.
If you are a Linux or macOS user, the device should work out of the box with the standard USB storage drivers. If it doesn’t, check dmesg for power management errors or try a different USB port.
Having the full VID/PID combination is your most powerful diagnostic tool. Don’t ignore it—use it to find the exact driver your hardware needs.
Have a different PID under the same vendor? Search for “Alcor Micro PID [your number]”. For PID 1234 specifically, the steps above remain the definitive guide.
Understanding USB Device ID: VID 058F PID 1234 The hardware identifier VID 058F PID 1234 is a common signature for USB flash drives and storage devices based on controllers from Alcor Micro Corp.. In the world of USB identification, the Vendor ID (VID) 058F uniquely identifies Alcor Micro Corp., while the Product ID (PID) 1234 often acts as a generic placeholder or default ID for various mass storage devices and flash disks. Technical Specifications
Devices with this ID typically belong to the USB 2.0 "High Speed" category. Because PID 1234 is frequently used across multiple Alcor-based products, the specific controller inside can vary. Common controller models associated with this hardware ID include: AU6986 / AU6988 AU6989SN SC708 (FC8708) / AU6987
These drives often appear under generic names like "USB Mass Storage Device" or "Generic USB Flash Disk" in your operating system's device manager. Manufacturers like Transcend frequently use Alcor controllers, which may lead to their JetFlash series appearing with these identifiers. Common Issues and Troubleshooting
Users searching for this specific ID often encounter errors where the drive is detected but inaccessible, showing "0 MB" capacity or a "No Media" error. 1. Device Not Recognized or Showing 0 Bytes
If your system detects the device but cannot access the storage, the internal firmware or file system may be corrupted.

The USB device ID VID 058F PID 1234 identifies a Flash Drive or Mass Storage Device manufactured by Alcor Micro Corp..
This specific combination is commonly associated with generic or "no-name" USB sticks and is frequently found in devices using Alcor Micro controllers, such as the AU698x series (e.g., AU6986, AU6988, or AU6989). Device Specifications Vendor ID (VID): 058F (Alcor Micro Corp.). Product ID (PID): 1234 (Flash Drive / Mass Storage). Device Type: USB Mass Storage Device (Flash Disk). Protocol Version: Typically USB 2.0 (High Speed). Controller Vendor: Alcor Micro. Common Uses and Issues
This ID is often seen in high-volume, generic flash drives. Because these IDs are programmable, they are sometimes found on "fake" or counterfeit drives where the reported capacity (e.g., 32GB) does not match the actual physical NAND flash storage.
Firmware Repair: If the drive shows "No Media" or "0MB" capacity, users often look for specialized "Alcor MP" (Mass Production) tools specifically for the AU69xx controller to reflash or repair the drive.
Driver Identification: Windows and other operating systems use this VID/PID to load the standard USB Mass Storage Class driver. No special third-party driver is usually required for basic operation. How to Verify Your Device
You can verify these identifiers on different platforms to confirm the hardware:
Windows: Right-click Start > Device Manager > Universal Serial Bus controllers > Right-click device > Properties > Details > Hardware IDs. Linux: Open a terminal and run the lsusb command. macOS: Go to About This Mac > System Report > USB. Flash Drive — USB 058F:1234 - DeviceHunt
