Download specialized low-level flash inspection tools like ChipGenius or Flash Drive Information Extractor.

Indicates version 1.0 of the device's firmware. Common Applications This identifier is frequently found in:

The same VID/PID combination also powers a more specialised device: the , a 4‑input, 4‑output USB 2.0 switch. This allows four computers to share four USB peripherals (printers, scanners, keyboards, etc.) without constant plugging and unplugging.

If you are still experiencing issues, try plugging the device into a different USB port to force a redetection, or check for BIOS updates to ensure the motherboard communicates correctly with the hub. If you're still having trouble, let me know: usb vid-214b amp-pid-7250 amp-rev-0100

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.

While the hardware string represents a standard architecture, real-world deployment on low-cost hubs exposes the device to connection or speed bottlenecks. 1. Device Drops Connection Under High Loads This allows four computers to share four USB

Indicates the first firmware version (v1.0) of the device silicon. Common Use Cases This chipset is frequently found in: Cheap, unbranded 4-port USB 2.0 hubs Internal USB headers on older motherboards. Front-panel SD/MicroSD card readers USB keyboards with built-in passthrough ports. ⚙️ Driver Requirements Because this device is a standard

This VID/PID pattern (VID 0x214B, PID 0x7250) corresponds to a USB audio/interface device from a small vendor that commonly uses the “amp-” prefix in descriptors to indicate an audio amplifier or USB audio interface (external DAC/amp, USB sound card, or portable headphone amplifier). The revision 0x0100 is a typical initial firmware/hardware revision.

While 214B is a legitimate ID traceable to TransMemory/Toshiba, users should be aware that: Upon checking the properties under the "Details" tab,

. Specifically, this Hardware ID is often associated with the HS8836A 4-port Hub chip Device Identification Vendor ID (VID) 214B: Associated with Huayi/Asix or generic Chinese USB controller manufacturers. Product ID (PID) 7250: Typically identifies a high-speed USB 2.0 hub controller Revision (REV) 0100:

This is the most critical identifier. Assigned by the USB Implementers Forum (USB-IF), it is a unique 16-bit number given to a specific vendor.

By understanding the USB VID-214B&PID-7250&REV-0100, you can better troubleshoot and manage your USB devices.

Automatically uses the native usbhub.sys driver included with all versions of Windows from XP to Windows 11.
