USB Device ID VID 058F PID 1234 a generic hardware identifier typically associated with flash drives using Alcor Micro Corp. controllers DeviceHunt Device Identification Vendor ID (VID) 058F : Identifies the manufacturer as Alcor Micro Corp. Product ID (PID) 1234
: A generic code often used when a device is in a "test" or "generic" state. While it commonly appears as "Mass Storage Device" "Generic USB Flash Disk," it can represent various flash drives from brands like DeviceHunt Common Issues
If your computer reports this specific VID/PID combination, it often indicates a firmware corruption or a device in emergency mode . Symptoms include: The drive shows as "No Media" or "0 MB" capacity.
Windows cannot format the drive or reports it is write-protected.
The device is recognized but cannot be opened in File Explorer. Recovery and Repair Tools
To restore a drive with these IDs, you must typically reflash the firmware using "Mass Production" (MP) tools specifically designed for Alcor controllers. Alcor Micro - USBDev.ru
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 you see Code 10 (Device cannot start)
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
USB Flash Drive Speed Tests - VID = 58f, PID = 1234 - NirSoft
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. Is VID 058F PID 1234 dangerous
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
