Alcor Micro USB Flash Drive (VID 058F, PID 1234) is a "Generic" mass storage device typically found in budget-friendly, unbranded, or promotional thumb drives. This specific hardware ID is notorious among tech enthusiasts for being associated with low-tier controllers that are frequently used in "fake capacity" drives or devices with high failure rates. Technical Overview Manufacturer: Generic / Alcor Micro Corp. Controller Vendor: Alcor Micro (common parts: AU6986, AU6988, or AU6989SN). Interface: USB 2.0 (High Speed). Current Draw: Max 100mA. Performance Review According to benchmark data from the NirSoft Speed Test Database , this device generally delivers a read speed around 9 MB/Sec

. While functional for small document transfers, it is significantly slower than modern USB 3.0 or high-performance USB 2.0 drives. Reliability: Users frequently report these drives showing 0 MB capacity

or failing after minimal use. They are "notorious for failing" and should not be used as a primary backup for critical files.

If the drive becomes corrupted, it often requires specific "AlcorMP" mass production tools to reset the firmware, which is a complex process for average users. Final Verdict

Extremely inexpensive; often given away for free as promotional items.

Very slow transfer speeds; high risk of data loss; prone to firmware corruption; frequently associated with fraudulent capacity ratings. Recommendation: Only use this device for disposable, non-critical data

(e.g., carrying a few PDFs to a print shop). If you need reliable storage, reputable brands from retailers like are far safer options. Are you trying to recover data from a corrupted drive with this ID, or are you looking to verify if a drive is fake

. While it often appears as a "Generic USB Flash Disk," this specific ID is a common fingerprint for a wide range of mass storage devices using Alcor controllers. What is this device? VID (Vendor ID) 058F belongs to Alcor Micro , a major manufacturer of USB controller chips. The PID (Product ID) 1234

is frequently used for their standard flash drive product line.

In many cases, this specific ID combination is seen on "no-name" or promotional USB sticks that use Alcor's AU698x series controllers. Common Issues and Symptoms

Users often search for this ID when their drive starts acting up. Typical symptoms include: "No Media" Error

: The computer recognizes the drive but shows 0 MB capacity. Write-Protection

: The drive becomes read-only and cannot be formatted through standard Windows tools. Corrupted Firmware

: 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

If you have discovered a device labeled VID 058F PID 1234 in your Device Manager, you are likely dealing with a Mass Storage Device powered by an Alcor Micro Corp. controller. This specific ID combination is famous in the tech world because it often appears when a USB flash drive has entered a "generic" or "emergency" mode due to firmware corruption or hardware failure.

Below is a full breakdown of what this ID means and how to handle it. Technical Breakdown: VID 058F PID 1234

Vendor ID (VID) 058F: This uniquely identifies the manufacturer as Alcor Micro Corp., a major producer of flash memory controllers.

Product ID (PID) 1234: This is a generic product code often used for Alcor-based Flash Drives and Card Readers.

Common Behavior: When a drive shows this PID, it may appear as "Generic USB Flash Disk" with 0MB capacity or be marked as "Write Protected". Why Is My Device Showing This ID?

There are three primary reasons your computer might see this specific ID:

Firmware Corruption: The internal software (firmware) of the USB controller has crashed, causing it to revert to a default "safe" identification mode.

Fake Flash Drives: Many counterfeit high-capacity drives use Alcor controllers. If the drive fails or is "reset," it often defaults to this ID.

Standard Operation: Some older Alcor-based card readers or OEM flash drives use this ID as their primary identifier. Troubleshooting and Drivers

If the device is not functioning correctly, follow these steps: 1. Identify the Specific Controller

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

The USB Device ID VID 058F PID 1234 identifies a flash drive utilizing an Alcor Micro Corp. controller. This specific combination is highly common in generic or unbranded USB mass storage devices and is frequently associated with firmware corruption issues, such as the "No Media" or "0 MB" error. 1. Device Identification & Specifications

This hardware profile typically indicates the following technical characteristics: Vendor ID (VID): 058F (Assigned to Alcor Micro Corp.)

Product ID (PID): 1234 (Generic Alcor Flash Drive identifier)

Controller: Often an Alcor Micro AU6989, AU6986, or AU6988 series. Protocol: Generally USB 2.0 High Speed. 2. Common Failures & Symptoms

If you are searching for this ID because your drive is malfunctioning, you likely see:

"No Media" Error: The drive is detected by the computer but shows as having no storage capacity in Disk Management.

Write Protection: The device is readable but cannot be formatted or written to.

Incorrect Capacity: A 32GB or 64GB drive may suddenly report 0MB or a significantly reduced size. 3. Deep Repair Guide (Firmware Flashing)

When standard tools like Windows Format or diskpart fail, you must use Mass Production Tools (MPTools) to re-flash the controller firmware. Step 1: Identify the Specific Controller

The VID/PID 058F/1234 is a generic "fallback" ID. To find the correct repair tool, you need the exact Controller Part Number and Flash ID.

Download a hardware info utility like ChipGenius or Flash Drive Information Extractor.

Look for the "Controller" (e.g., AU6989SN) and "Flash ID" (e.g., 89A46432). Step 2: Locate the Correct MPTool

Search for an Alcor Micro MPTool specifically matching your controller part number. Reliable databases for these utilities include sites like USBDev.ru or MyDigit. Step 3: Flashing the Drive

Extract and Run: Open the MPTool application as an Administrator.

Detection: Plug in your USB; it should appear in one of the numbered slots in the tool's interface.

Setup/Configuration: If the drive isn't recognized, you may need to enter "Setup" (often the password is blank or "0000") and ensure the VID and PID are set to 058F and 1234.

Start Flashing: Click Start or Execute. This process completely wipes the NAND and reinstalls the controller's instructions. 4. Basic Troubleshooting Alternatives

Before attempting high-risk firmware flashing, try these standard repairs:

. These identifiers are critical for technicians attempting to recover data or repair "dead" flash drives that are no longer recognized by operating systems. Technical Specifications

When a device with these IDs is connected, it generally reports the following hardware profile: Vendor ID (VID): (Alcor Micro Corp.) Product ID (PID): Manufacturer: Product Model: USB Flash Disk / Mass Storage Device Common Controllers: Alcor Micro AU6986, AU6988, or AU6989SN series USB Version: USB 2.0 (High Speed) Common Use Cases and Problems

This specific VID/PID combination is often found in unbranded or "white-label" USB sticks. Users frequently encounter this ID when troubleshooting a device that shows "0 MB" capacity or "No Media" in Disk Management. In many cases, seeing

can indicate the controller has entered a "fail-safe" or "test" mode because the firmware is corrupted or the flash memory chip has failed. Troubleshooting and Repair

If your computer detects the drive but cannot access it, the following steps are commonly used by the tech community: Driver Reinstallation: Windows Device Manager to uninstall the "USB Mass Storage Device" entry under Universal Serial Bus controllers

and restart your PC to let Windows reinstall it automatically. Controller Identification: Use utilities like ChipGenius Flash Drive Information Extractor to confirm the exact Alcor controller model. Low-Level Formatting:

For corrupted firmware, specialized "Alcor MPTool" (Mass Production Tool) versions are often used to reflash the controller. Note that these tools are third-party and may cause permanent hardware damage if used incorrectly. Disk Cleaning: If the issue is a logical partition error, the Diskpart utility can be used to the drive and create a new primary partition.

Attempting to repair a flash drive with production tools will permanently delete all data on the device. specific version of the Alcor MPTool compatible with your controller's part number?
