If you are seeing this specific combination of Vendor ID (VID) and Product ID (PID) in your device manager, it typically points to inexpensive, unbranded, or promotional thumb drives powered by controllers like FirstChip.
Below is a drafted blog post exploring what these IDs mean, why they are so common, and how to optimize or troubleshoot these specific drives. Unmasking the Mystery USB: What is VID 346d & PID 5678?
Have you ever plugged a generic, no-name USB flash drive into your computer, dug into the hardware properties, and found the identifiers
? If you are scratching your head trying to figure out who actually made your thumb drive, you are not alone.
This specific combination of Vendor ID and Product ID is one of the most common sights in the world of budget and promotional USB storage. Let’s pull back the curtain on what these numbers mean and how you can get the best performance out of these mystery drives. What Do These Numbers Actually Mean?
In the USB world, every device carries two digital thumbprints so your operating system knows what it is and what drivers to use: VID (Vendor ID):
usually traces back to generic mass-production firms or a bridge controller company often referred to in logs as PID (Product ID):
is the placeholder product code assigned to these mass-produced storage drives.
If your drive says this, you likely have a drive running a controller made by companies like
(such as the FC1178 or FC1179). These parts are the backbone of millions of unbranded flash drives, cheap bulk-buy sticks, and the free corporate giveaway drives you receive at conferences. The Good, The Bad, and The "Fake"
Because these hardware IDs are tied to low-cost controllers, they come with a few quirks you should be aware of: They are incredibly cheap: Here is the decoded information from your text
They serve perfectly well for moving small PDF files, school documents, or small media files. They are slow:
Do not expect top-tier solid-state speeds. These are built for cost-efficiency, not high-speed data transfers. Watch out for capacity spoofing:
Because the FirstChip controllers are highly programmable, dishonest third-party sellers sometimes use them to create "fake capacity" drives. They might take a physical 16GB or 64GB memory chip and program the controller to tell your computer it is a 1TB drive. As soon as you fill it past its true capacity, your data starts corrupting! How to Get the "Best" Out of Your 346d/5678 Drive
If you own one of these drives and want to ensure you are getting the safest and best experience possible, follow these three steps: 1. Test it for Fake Capacity First
Before putting any important photos or documents on a generic drive, test its true boundaries. Use a free tool like (for Windows) or
(for Mac/Linux). These programs fill the drive with data and read it back to verify if the advertised storage matches the actual hardware. If it fails, throw the drive away or demand a refund! 2. The File System Trick (FAT32 vs. exFAT)
Many users on tech forums have noted that these specific VendorCo PID 5678 drives come formatted as standard FAT32. If you format the drive to , you may notice a slight bump in write and read speeds.
Formatting to exFAT also removes the annoying 4GB individual file size limit that FAT32 carries! 3. Treat it as Temporary Storage
Because the controller and flash memory used in these highly generic devices are built to be as inexpensive as possible, they have a higher failure rate than name-brand drives (like SanDisk, Kingston, or Samsung).
Never use a VID 346d PID 5678 drive as your only backup for important data.
Use them for temporary transfers, and keep your permanent files safely tucked away on a verified external hard drive or cloud service. Further Exploration

Understanding VID and PID: The Case of VID 346D and PID 5678
In the world of computer hardware and peripherals, devices are often identified by unique codes to facilitate communication and driver installation. Two critical identifiers in this context are the Vendor ID (VID) and the Product ID (PID). These IDs are crucial for both device manufacturers and users, as they help in ensuring that the correct drivers and software are matched with the specific hardware.
What are VID and PID?
Vendor ID (VID): This is a unique 4-digit hexadecimal code assigned to a company by the USB Implementers Forum (USB-IF). It identifies the vendor of a USB device. For instance, VID 346D might be associated with a particular company that develops USB devices.
Product ID (PID): This is another 4-digit hexadecimal code that, when combined with the VID, uniquely identifies a specific product from a vendor. Therefore, PID 5678 would correspond to a specific product line from the company with VID 346D.
The Significance of VID 346D and PID 5678
When looking for drivers or software for a device, users often need to provide the VID and PID to ensure they get the correct and compatible version. In the case of VID 346D and PID 5678, this would typically mean:
Device Recognition: The operating system uses these IDs to recognize the device and to decide which driver to load. A correct match ensures that the device functions properly.
Driver Installation: Users might need to manually install drivers for their device. Knowing the VID and PID helps in downloading the right drivers from the manufacturer's website or other reliable sources.
Troubleshooting: In case of device malfunction or incompatibility issues, having the VID and PID can help in troubleshooting, as it allows for precise identification of the device in question.
Best Practices for Using VID and PID
Always Verify: Before downloading drivers or software, ensure that you have the correct VID and PID for your device.
Manufacturer’s Website: For safety and compatibility, it's best to download drivers and software directly from the device manufacturer's website. Vendor ID (VID): 346D Product ID (PID): 5678
Caution with Third-Party Sites: Be cautious when using third-party websites, as they might bundle drivers with additional software that could potentially harm your system.
The search for "vid+346d+pid+5678+best" indicates a technical interest in USB Flash Drive performance, specifically identifying hardware by its Vendor ID (VID: 346d) and Product ID (PID: 5678). These identifiers are most commonly associated with generic or "no-name" controllers, often found in drives like the Kingston DTSE9H or unbranded clones. The "Mystery Drive" Story
Once there was a photographer who found a "too good to be true" deal on a 64GB USB 3.0 flash drive. When they plugged it in, the computer identified it with the tags VID: 346d and PID: 5678.
At first, the drive seemed perfect—it was small, sleek, and held all their recent shoots. But as the photographer began transferring large batches of high-resolution RAW files, they noticed something strange: the speed started high but plummeted after just a few minutes.
To solve the mystery, they turned to technical communities and performance databases like the USB Flash Drive Speed Tests, which track real-world results for specific VID/PID combinations. Useful Takeaways for Your Tech
If you are looking for the "best" way to handle a drive with these IDs, keep these points in mind:
Real vs. Official Size: Generic drives often show a capacity (like 4GB) that is larger than the actual usable space (often around 3.7GB). This is due to the way manufacturers calculate gigabytes versus how your computer reads them 0.5.1.
Sequential vs. Small Files: Tools like USBDeview test speed by writing one large file. You will get the "best" speeds with large video files; however, if you try to move thousands of tiny photos, the speed will drop significantly 0.5.2.
Reliability Check: Because these specific IDs (346d/5678) are often used by many different manufacturers, it is "best" to test your specific unit. You can use the USB Speed Test Database to compare your results with others who have the same hardware fingerprint 0.5.3.
The hardware identifiers VID 346D and PID 5678 correspond to a generic USB flash drive, often marketed under names like "Disk 2.0" or "VendorCo ProductCode". These devices typically utilize controllers from FirstChip (such as the FC1178 or FC1179) and are frequently found in budget-friendly or promotional unbranded USB sticks.
To get the best performance and reliability out of these specific devices, follow the optimization and recovery guide below. 1. Identify Your Device Specifications
The "best" way to manage this device is to know exactly what is under the hood. Since VID 346D/PID 5678 is a generic identifier, manufacturers often use it for various memory chips.
Controller: Most commonly uses the FirstChip FC1178/FC1179 series.
Real Capacity Check: Some budget drives with these IDs are "fake capacity" drives (e.g., a 16GB chip programmed to report as 64GB). Use tools like H2testw to verify the actual storage space before trusting it with important data. 2. Best Performance Settings: exFAT vs. FAT32
While many of these drives come formatted as FAT32, user tests suggest that switching to exFAT can significantly improve transfer speeds for larger files. Read Speeds: Typically range around 19 MB/s.
Write Speeds: Often average around 6.5 MB/s.Formatting with a larger allocation unit size in exFAT may help bridge the gap if you frequently move video files or large backups. 3. Drivers and Maintenance
Windows generally includes generic USB Mass Storage Class drivers that support this VID/PID automatically.
Driver Fixes: If the drive isn't recognized, you can manually update it via Device Manager by selecting "USB Mass Storage Device" and using the "Update Driver" function.
Power Management: To prevent the drive from disconnecting during long transfers, uncheck "Allow the computer to turn off this device to save power" in the device's Power Management tab within Device Manager. 4. Recovery: "The Best" Repair Tools
If your VID 346D PID 5678 drive becomes "Write Protected" or shows "No Media," it often indicates a firmware glitch. The industry-standard tool for reviving these FirstChip-based drives is the FirstChip MpTools. Download the version compatible with FC1178 or FC1179.
Run a "Factory Scan" to reset the controller to its original state.
Note that this will erase all data, but it is often the only way to make a "bricked" drive usable again.
