Usb — Vid214b Amppid7250 Amprev0100 New Fix

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.

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 vid214b amppid7250 amprev0100 new

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.

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

What If Nothing Works?

There is a possibility that the hardware is faulty or the dongle is a generic "no-name" clone using spoofed IDs. In this case: The USB device identified as VID 214b ,

• Test on another PC: If it fails on a second machine, the hardware is likely dead.
• Check the SIM card: Ensure the SIM is inserted correctly and has active data service. Some dongles show driver errors if no SIM is detected.
• Consider an upgrade: 4G/5G dongles with native Windows 11 drivers cost under $30 today.

Why This Matters: The Democratization of Archiving

Devices carrying the VID_214B identifier are rarely "professional" equipment. They are consumer-grade, often costing under $20. Yet, this affordability is their greatest feature.

Professional video capture cards from brands like Blackmagic Design or Elgato can cost hundreds of dollars—overkill for a user wanting to digitize a handful of family holiday tapes. The VID 214B adapter democratizes the process. It puts video preservation into the hands of anyone with a laptop and a USB port.

Troubleshooting Guide: Decoding USB VID_214B&PID_7250&REV_0100

Posted by TechSupport Team | Reading time: 4 minutes

Have you ever opened Device Manager on your Windows PC, expanded the "Universal Serial Bus controllers" or "Other devices" section, and found a yellow triangle next to an unknown device? If the hardware IDs read USB\VID_214B&PID_7250&REV_0100, you are not alone.

This cryptic string isn't a random error—it is a specific fingerprint for a piece of hardware. In this post, we will break down what this ID means, why it is showing up without a driver, and how to fix it.

The Technical Limitations

It is important to manage expectations for the REV_0100 hardware. These adapters generally capture video at standard definition (480i or 576i). They utilize a CMOS sensor that is sensitive to light but can struggle with high-motion scenes or low-light VHS tapes, often resulting in grain or "ghosting" artifacts. They do not support HD upscaling natively; that work must be done via software post-processing.

However, for the massive majority of archival work—saving family memories or preserving old home videos—the trade-off between quality and price is more than acceptable.

If you want deeper help

Provide:

• Your OS (Linux/macOS/Windows) and kernel/OS version.
• Output of lsusb -v -d 214b:7250 (or Device Manager hardware IDs / System Information).
• Any visible vendor strings from device descriptors or product labels.

If you’d like, I can help interpret descriptor output or suggest exact driver modules—paste the device info and your OS.

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.
