The identifiers USB\VID_214B&PID_7250 refer to a standard USB 2.0 High-Speed Hub

. This specific hardware combination is frequently found in various multi-port devices, including standalone USB hubs, KVM switches, and docking stations. Technical Identification Vendor ID (VID) 214B : This ID is typically associated with Huizhou Huada Magnetoelectric Co., Ltd.

, manufacturers often producing generic hub controller chips like the Product ID (PID) 7250 : This specific PID identifies the device as a 4-port USB 2.0 Hub Revision 0100 (REV_0100)

: This indicates the initial hardware version of the chip's firmware or hardware revision. Common Applications

Devices using these identifiers are often unbranded or white-labeled products. They appear in: AIMOS KVM Switches : Specifically the 4-in 4-out USB switch. Generic USB Hubs : Such as the GINZZU GR-315UB or other budget-friendly 4-port expansion hubs. Embedded Systems : Often seen in Linux logs on devices like the Raspberry Pi when an external hub is connected. Driver and Troubleshooting Because this is a standard class-compliant USB Hub, it does not require proprietary drivers

for modern operating systems like Windows 10/11, macOS, or Linux. : Recognized automatically as a Generic USB Hub : Identified via as a "USB2.0 HUB". Common Issues

: If the device fails to enumerate (often appearing as "Unknown USB Device" or showing an error in Device Manager), it is usually due to power insufficiency for the connected peripherals or a physical failure in the hub's internal HS8836A controller chip. For further verification, you can check the USB ID Repository or use the DriverIdentifier database to confirm the hardware match for your specific machine. Are you experiencing a specific connectivity error driver failure with this device? 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. usb vid214b amppid7250 amprev0100 new

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: Method 1: Use the Virtual CD-ROM (The Easiest

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.

Are you looking to integrate this hub into a specific project (e.g., Raspberry Pi or custom PCB) or are you having trouble getting it recognized? Generic USB Hub Driver for HP - DriverIdentifier

This specific hardware ID refers to a USB 2.0 Hub typically powered by the Huasheng Electronics HS8836A chipset. You will commonly see this identifier in budget 4-port hubs, USB-to-Ethernet combo adapters, or specialized USB switches like those from brands like AIMOS. Device Breakdown VID 214B: Assigned to Huasheng Electronics.

PID 7250: Specifically identifies the HS8836A 4-Port Hub chip.

REV 0100: Indicates the first hardware revision of this specific product. Driver & Setup Guide Open File Explorer (Win + E)

Since this is a standard "Generic USB Hub," it does not require proprietary drivers on modern operating systems.

Method 1: Use the Virtual CD-ROM (The Easiest Fix)

Most Huawai dongles contain the drivers inside their own flash memory.

1. Open File Explorer (Win + E).
2. Look for a new CD/DVD drive letter (e.g., "Mobile Partner" or "Huawai Setup").
3. Double-click the AutoRun.exe or Setup.exe file.
4. Follow the installation wizard.
5. After installation, unplug and replug the dongle.

Troubleshooting notes

• If the device is not working: confirm VID/PID, check dmesg for errors, verify a matching driver exists, and check whether the firmware revision requires an update.
• If VID/PID are unknown: look up the VID (0x214B) in a USB vendor database to identify the manufacturer, then search that vendor’s documentation for PID 7250.

Manual Driver Installation via INF File

If Windows fails to auto-detect, you can manually force it:

1. Download a generic Anyka 7250 driver (from a trusted GitHub repo or tech forum like Badcaps.net).
2. Extract the .inf and .sys files.
3. Right-click the .inf file → Install.
4. Or, in Device Manager: Right-click the unknown device → Update driver → Browse my computer → Let me pick → Have disk → Point to the .inf.

The State of Native Drivers

• Windows 10 & 11 (Modern Versions): Should work immediately via the native Microsoft USB Video Class (UVC) driver. If you see a yellow bang, the device is either faulty, using a proprietary protocol, or your Windows installation is corrupted. Try Windows Update → Optional Updates → Driver Updates.
• Windows 7 & 8: Often problematic. Microsoft’s UVC driver is present, but many Anyka 7250 devices require a vendor-specific .inf file to enable resolutions above 640x480 or to activate the microphone.
• Linux (Ubuntu, Debian, Arch): Typically works out-of-the-box with the uvcvideo kernel module. Run lsusb to verify. If not working, update your kernel (sudo apt update && sudo apt upgrade).
• macOS: Limited support. Some users report success with generic USB camera kexts; others need third-party apps like CamTwist or OBS to force a connection.

2. PID (Product ID) – 7250

• What it is: A number assigned by the manufacturer (Anyka) to distinguish a specific product model or chip family.
• What 7250 points to: The Anyka AK7250 series is a known chipset for USB cameras. Search queries for PID_7250 commonly link to:
  • "No-name 1080P USB webcam"
  • "Endoscope camera for Android/PC"
  • "DIY microscope camera module"
  • "Video grabber with microphone"

What Do the Codes Mean?

• VID (Vendor ID): 214B is registered to "HID Interface Design" (or a closely associated OEM partner). This vendor specializes in reference designs for custom keyboards, point-of-sale (POS) scanners, and industrial control panels.
• PID (Product ID): 7250 falls within a block reserved for "Multi-touch Digitizer / Configurable Macro Pad."
• REV (Revision): 0100 indicates this is the first production hardware revision, likely released to manufacturing in late Q4 2025.

Bridging the Analog Divide: Inside the USB Video Capture Adapter (VID 214B / PID 7250)

By [Your Name/Tech Correspondent]

In an era defined by 4K streaming and cloud storage, it is easy to forget the mountains of analog media gathering dust in closets around the world. From wedding tapes on VHS-C to classic Nintendo gameplay recorded on VCRs, millions of hours of history are trapped on magnetic tape. Enter the unassuming hero of digital preservation: the USB Video Capture Adapter.

Identified in Windows Device Manager by the hardware IDs USB\VID_214B&PID_7250&REV_0100, this device represents one of the most ubiquitous and vital tools for media archiving. While it may look like a simple USB stick with RCA connectors, the technology inside—and the software ecosystem surrounding it—tells a fascinating story of accessibility and reverse-engineering.

Scenario C: A Video Capture Card

Low-cost HDMI-to-USB or AV-to-USB capture dongles (e.g., "EasyCAP" clones) sometimes rebrand Anyka chips. If your device has RCA (yellow/red/white) or HDMI input, this is your product.
