Fix 5: Hardware Troubleshooting

If software fixes don’t help, consider hardware:

  • For internal card readers: Power off, open the laptop (if comfortable), reseat the small flat ribbon cable connecting the card reader board to the motherboard.
  • For external USB hubs: Try a different USB port, preferably a powered USB port or use a powered hub.
  • For desktop PCs: Update the chipset and USB controller drivers from Intel or AMD.

Quick reference

  • VID: 0x058F — Alcor Micro (commonly)
  • PID: 0x1234 — generic/product-specific; often used for commodity flash/card-reader devices
  • Typical classes: Mass Storage, Vendor-specific; check descriptors to confirm.

If you want, I can analyze a descriptor dump from your system (paste the lsusb -v output or a USBView dump) and explain the fields and recommended drivers.

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 usb device id vid 058f pid 1234 full

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

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.

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.

Identify the Controller: Use a tool like ChipGenius to find the specific "Controller Part-Number" (e.g., AU6989SN, AU6986). Troubleshooting Your "Generic" USB: Identifying VID 058F &

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:

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. Fix 5: Hardware Troubleshooting If software fixes don’t

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

USB Device ID VID 058F PID 1234 Full: Drivers, Issues, and Complete Identification Guide

Why Does It Show as "Unknown Device" with an Error?

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

  • Missing or Corrupt Driver: Windows does not include a native driver for every Alcor variant. You may need the specific chipset or card reader driver from your PC manufacturer.
  • Driver Conflict: Another USB or storage driver has taken control of the same resources.
  • Hardware Malfunction: The internal card reader’s ribbon cable is loose, or the chip is damaged.
  • Improper USB Hub Power: An external hub using the 058F:1234 chip may not be receiving adequate power.

When to Give Up and Disable the Device

If after all attempts the device still shows an error and you do not use the card reader or USB hub, disable it to remove the yellow bang from Device Manager:

  1. Right-click the device → Disable device.
  2. This stops Windows from trying to load a driver for it.

Disabling is harmless. You can re-enable it later if you find a solution.
