The hardware identifier USB\VID_214B&PID_7250&REV_0100 identifies a USB 2.0 Hub controller, typically manufactured by Ameco Technologies (Shenzhen) Co., Ltd. or Huasheng Electronics. This specific ID is common in budget-friendly hardware like 4-port USB splitters, KVM switches, and integrated hubs within some laptops, such as the HP Laptop 15-db1xxx. Understanding the Hardware ID
A USB hardware ID is a diagnostic string that tells your operating system exactly what hardware is plugged in so it can load the correct software.
VID_214B (Vendor ID): Assigned to Ameco Technologies (Shenzhen) Co., Ltd..
PID_7250 (Product ID): Specifies the exact device, which is a USB 2.0 Hub.
REV_0100 (Revision): Indicates the firmware version or hardware revision (v1.0). Driver Information and Compatibility
For most users, no manual driver installation is required for this device. Because it is a generic USB hub, modern operating systems like Windows 10/11, macOS, and Linux include built-in drivers that automatically recognize and configure it upon connection.
If the device appears in the Windows Device Manager with an error, it is often listed as a Generic USB Hub or USB2.0 HUB. Common Troubleshooting Steps

Understanding USB\VID_214B&PID_7250&REV_0100: Identification and Solutions
The hardware ID USB\VID_214B&PID_7250&REV_0100 identifies a common USB 2.0 High-Speed Hub controller. This specific combination of Vendor ID (VID), Product ID (PID), and Revision (REV) is frequently found in affordable USB peripherals, such as 4-port hubs, KVM switches, and docking stations. Technical Identification
Vendor ID (VID) 214B: Assigned to Huasheng Electronics (also referred to as Huazhi or Huasheng).
Product ID (PID) 7250: Identifies the device as a USB 2.0 Hub.
Chipset Information: This hardware ID is often associated with the HS8836A 4-port hub chip. It is a budget-friendly controller used in various generic and branded USB expansion products like those from AIMOS or GINZZU. Driver and Compatibility
Devices using this ID are "Class 09" devices, meaning they are standard USB hubs. usb vid214b amppid7250 amprev0100 new
Plug-and-Play: You typically do not need to download a custom driver for this device. Windows, macOS, and Linux all include a built-in Generic USB Hub driver that supports this hardware automatically.
Speed Limitations: While some modern devices using this chip may be marketed as USB 3.0, the 7250 PID often specifically indicates a USB 2.0 internal connection, which may limit data throughput to 480 Mbps. Troubleshooting Common Issues
If your computer shows an "Unknown Device" or a yellow exclamation mark for this ID, it is usually a connectivity or power issue rather than a missing driver. Huasheng Electronics — USB Vendor 214B - DeviceHunt

The USB device identified as VID 214b, PID 7250, with Revision 0100 is a generic high-speed 4-port USB 2.0 Hub controller, typically powered by the Huasheng Electronics HS8836A chip.
This specific hardware ID is frequently found in affordable desktop peripherals, such as the AIMOS AM-UK404 4x4 USB switch and various generic 4-port hubs like the GINZZU GR-315UB. Below is a detailed breakdown of what this ID means for your system and how to handle it. Technical Breakdown of the Identifiers
A USB Hardware ID is the "fingerprint" your computer uses to determine which driver to load.
VID (Vendor ID) 214b: Registered to Huasheng Electronics (also sometimes listed as Ameco Technologies).
PID (Product ID) 7250: Specifically identifies a 4-port USB 2.0 Hub.
REV (Revision) 0100: Indicates the hardware version (v1.00) of the controller chip. Typical Use Cases & Components
This controller is extremely common in multi-port accessories because it is cost-effective and provides standard "Plug and Play" functionality. You will most often find it inside:
USB Switches: Devices that allow multiple computers to share the same set of USB peripherals (e.g., keyboards and mice).
Combo Adapters: USB-to-Ethernet adapters that also include three or four extra USB ports. Introduction: The Mystery of the String If you
Internal Hubs: Built-in ports on monitors or laptop docking stations. Driver & Troubleshooting Information
Because this device is a standard USB 2.0 hub, it does not require proprietary drivers for modern operating systems.
Windows/macOS/Linux: The system should automatically load the generic "USB Root Hub" or "Generic USB Hub" driver.
Common Issue (Intermittency): Some users report that these hubs can be recognized inconsistently, particularly when used with Raspberry Pi or Linux systems. This is often due to power instability or the hub being "bus-powered" (drawing power only from the computer) rather than having its own external power adapter.
Identification Tool: If you need to verify the chip details further, tools like the Flash Drive Information Extractor or USBDeview can provide deeper technical logs.
Are you experiencing connectivity issues with this hub, or do you need help locating a specific firmware update for a device using this ID?

If you are reading this, you have likely opened your Windows Device Manager, Linux dmesg log, or USB diagnostic tool and been confronted with a cryptic string: USB\VID_214B&PID_7250&REV_0100. Perhaps it is accompanied by a yellow exclamation mark, labeled as "Unknown Device," or is being flagged as a "New" hardware detection.
For the average user, this alphanumeric soup is intimidating. For a technician, developer, or hardware enthusiast, it is a precise fingerprint—a digital DNA that tells the exact story of a piece of hardware plugged into your system.
This article will dissect every component of this identifier, explain what it means, why it appears as "NEW," how to find the correct driver, and what to do if it isn’t working.
