If you see USB\VID_214B&PID_7250&REV_0100 with a Code 28, 43, or 10, work through this checklist:
If you are on Windows 10 or 11, the driver is often included in the standard update catalog.
The identifier USB\VID_214B&PID_7250&REV_0100 is intimidating to look at, but it is just Windows saying, "I found a Huawai modem, but I don't know how to talk to it."
In 90% of cases, running the setup from the virtual CD-ROM that appears when you plug the device in will solve the problem instantly. If not, manually pointing Windows to the driver folder on that same virtual drive will do the trick.

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 usb vid214b amppid7250 amprev0100 new
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.
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.

USB hub only recognised intermittently - Raspberry Pi Forums
Once upon a time, in the labyrinth of a computer's motherboard, a new traveler arrived: the USB Device VID 214B, PID 7250.
To the operating system, this traveler looked like a "Generic USB 2.0 Hub" or a high-speed connection point. It was a humble but essential piece of hardware, often powered by a Chipsbank Microelectronics chip (like the HS8836A). Its job was simple: to take one single USB port and expand it, allowing four other devices to find a home and speak to the computer. But sometimes, the traveler faced challenges:
The Recognition Crisis: Occasionally, a computer would see it but not know its name, labeling it an "Unknown USB Device". In these moments, the computer needed a quick "refresh" by reinstalling the driver through the Device Manager.
The Power Struggle: If the traveler was part of a "powered hub" but couldn't get enough energy, it might stop the whole system from booting properly. The fix was often a simple power cycle or checking the physical connection for damage.
The Silent Treatment: Sometimes the hub would work for a card reader but give the "silent treatment" to a mouse or keyboard. This usually meant the system needed a driver update or a change in power management settings to keep the port "awake". Generic USB Hub Driver for HP - DriverIdentifier

Some Linux users have reported intermittent recognition on Raspberry Pi devices, often related to power supply issues or standard implementation differences. diagnosing a connection error for this hub? Generic USB Hub Driver for HP - DriverIdentifier
The hardware string USB\VID_214B&PID_7250&REV_0100 identifies a Generic USB 2.0 Hub. This specific Vendor ID (214B) is associated with Huasheng Electronics or Huaxin (Zhuhai) Technology, and the PID 7250 is typically used for the HS8836A 4-port hub chip.
This device is a "class-compliant" 4-port hub, meaning it does not require proprietary drivers and should work out-of-the-box on modern operating systems. Device Summary Manufacturer: Huasheng Electronics / Huaxin (Zhuhai) Chipset: HS8836A Function: USB 2.0 High-Speed 4-Port Hub Hardware ID: USB\VID_214B&PID_7250&REV_0100 Implementation & Deployment
Since this is a standard hub, the "complete feature" usually refers to ensuring it is correctly enumerated and powered by the host system. 1. Drivers (Windows)
Windows uses the built-in usbhub.sys driver for this device. If the device appears as "Unknown" in Device Manager, you can force the standard driver: Right-click the device and select Update driver.
Choose Browse my computer for drivers > Let me pick from a list of available drivers. Select Generic USB Hub. 2. Identification (Linux/macOS)
On Linux, you can verify the device connection using the terminal: Command: lsusb -d 214b:7250
Expected Output: Bus XXX Device XXX: ID 214b:7250 Huasheng Electronics USB2.0 HUB 3. Troubleshooting Issues
If the hub is failing to recognize connected devices (common with "error -71" in Linux logs), consider these steps:
Power Supply: Ensure the hub is receiving adequate power. Bus-powered hubs may fail if they attempt to power multiple high-draw devices (like external HDDs) simultaneously.
Port Cycling: For Raspberry Pi or embedded systems, you may need to force a power cycle on the upstream port if the device fails to enumerate.
Cable Quality: Ensure the USB cable is a shielded "High-Speed" (480 Mbps) cable. Cheap cables often cause signal degradation with this specific chipset.

Date: April 19, 2026 Category: Hardware Forensics / Peripheral Analysis
A new USB device signature has appeared in driver enumeration logs and hardware databases this quarter, identified by the unique pair VID_214B and PID_7250, with a revision identifier of REV_0100.
For system administrators and hardware tinkerers, this VID/PID combination presents an interesting case: it does not immediately map to a major consumer brand like Logitech, Dell, or SanDisk. Instead, it points toward the growing market of generic Human Interface Devices (HIDs) and white-label hardware.
This string appears to be a technical device identifier and status line commonly produced by USB enumeration tools, kernel logs, or device firmware messages. I'll break it into components, explain each part, and give examples of how and where you might see such a line.
