This represents the Vendor ID. VID 214B is registered to Qingdao Huayu Information Technology Co., Ltd. , a company that produces components often utilized in electronic assemblies, including USB hubs.

This internal chip is found in various unbranded and branded USB accessories, including: AIMOS AM-UK404: A 4-port USB 2.0 KVM switch. GINZZU GR-315UB: A standalone 4-port USB hub. Embedded Hubs: Often found inside larger devices like all-in-one PCs (such as HP or ASUS series), or display docks that provide additional USB ports. Driver Information Because this is a standard USB Hub, it is "plug-and-play"

Want to confirm that you have this device on your own computer? Here’s how:

When your operating system reads this hardware string, it decodes the raw technical data to determine how to communicate with the hardware. A breakdown of the hardware descriptor reveals: usb vid-214b amp-pid-7250 amp-rev-0100

You almost never need to download a separate driver from the manufacturer. However, if you’re using a specific device like the AIMOS AM‑UK404 that has extra switching logic, check the manufacturer’s website for any optional utility software.

Before diving into fixes, it is crucial to understand what this hardware signature represents. Vendor ID (VID) 214B: Identifies the manufacturer as Huayi Electronics Co., Ltd. (or associated generic Chinese manufacturers like Product ID (PID) 7250: Identifies the specific model, usually a USB 2.0 Hub Multi-Slot Card Reader Controller Revision (REV) 0100:

: This indicates the first firmware version (v1.00) of the chip. Where You’ll Find It This represents the Vendor ID

Download and install the latest for your specific model. Conclusion

Isolate the operating system's software layer from the physical ports by forcing a complete reset of the USB hub stack. Press Windows Key + X and select .

Additionally, these IDs help identify "fake" drives. Fraudulent sellers sometimes program cheap, low-capacity drives to report a higher capacity to the OS. If a supposed "1TB drive" reports a VID/PID combination associated with a cheap 8GB controller model, it is an immediate red flag. This internal chip is found in various unbranded

Before solving the problem, you must understand the anatomy of a USB Hardware ID.
