If you have landed on this page, you have likely opened the on your Windows computer, expanded "Universal Serial Bus controllers" or "Other devices," and found a yellow exclamation mark next to an unknown device. Upon checking the properties under the "Details" tab, you saw the hardware ID:
Hold the physical power button down for 30 consecutive seconds to drain residual capacitance from the motherboard's capacitors. usb vid-214b amp-pid-7250 amp-rev-0100
Based on the hardware identifiers provided, here is the "story" of your device: If you have landed on this page, you
Look for the generic USB Hub driver (often named USB20_HUB or similar) that matches the VID_214B and PID_7250 parameters. Download and install the driver. Method 2: Manually Installing the Generic USB Driver Download and install the driver
This device ID string — USB VID_214B PID_7250 REV_0100 — identifies a specific USB product and revision. Below I review what that identifier implies, how to interpret and troubleshoot it, and practical examples of real-world workflows for users and developers interacting with such a device.
: This is often tied to inadequate current delivery or missing initialization states. Connect the hub after the OS has fully loaded. If using multiple high-draw devices (like external hard drives), always swap the passive unit for an externally powered USB hub to stabilize the connection. 3. Power Surge on the USB Port
In simpler terms, this identifier points to a component often found integrated into laptops—particularly HP laptops—or external USB peripherals. Why Is This Driver Appearing?
