controller. This hardware is often found in both standalone multi-port hubs and as an integrated component within other devices like keyboards, monitors, or docking stations. STMicroelectronics Community Device Identification Vendor ID (VID) 214b : Manufactured by Huasheng Electronics (also associated with Ameco Technologies Shenzhen). Product ID (PID) 7250 : Specifically identifies a 4-port High-Speed (HS) Hub Revision (REV) 0100 : Indicates the initial firmware or hardware version ( STMicroelectronics Community Key Features Plug and Play : This device typically uses the native Generic USB Hub
: The Vendor ID assigned to the manufacturer Huasheng Electronics / Ameco .
The code usb vid-214b amp-pid-7250 amp-rev-0100 identifies a simple, functional, and extremely common USB 2.0 hub from Huasheng Electronics. It works out of the box on nearly all operating systems, making it a convenient solution for expanding your USB ports. However, its performance is strictly limited to USB 2.0 speeds, and its build quality can be inconsistent, leading to occasional reliability issues. It is a budget-friendly device that works best for low-bandwidth peripherals like a mouse and keyboard, but it is not suitable for demanding tasks.
Yes. Linux (kernel 3.x+) should recognize it as usb-storage automatically. If not, run sudo modprobe usb-storage . macOS will treat it as a generic external drive. No drivers needed. usb vid-214b amp-pid-7250 amp-rev-0100
The string USB VID-214B & PID-7250 is more than just random code; it is a digital serial number that connects a physical piece of silicon to the logic of a computer. For the average user, it represents a reliable Toshiba-based flash storage device. For the technician, it is a crucial key for unlocking drivers, performing repairs, and verifying hardware authenticity.
– This ID belongs to Huasheng Electronics . They are a common manufacturer of low-power USB controller chips used in a wide variety of generic and brand-name electronics.
Every Universal Serial Bus device contains standardized hardware descriptors mapped inside its EEPROM. This specific string breaks down into three distinct blocks of highly critical data: controller
Linux distributions map the hardware dynamically inside the kernel using the core usb-storage and hub modules. When executing the lsusb command, the environment queries the device descriptors and populates the text output directly:
When connecting peripherals to a computer, Windows often identifies devices through a Vendor ID (VID) and Product ID (PID). One such identifier that frequently appears in device manager logs, especially during driver troubleshooting on HP laptops and other devices, is .
) or standard Linux hub drivers. If the device is not working: Power Cycle: Product ID (PID) 7250 : Specifically identifies a
This is a 16-bit number chosen by the vendor to identify a specific product model.
: Users on platforms like the Raspberry Pi Forums have reported that this hub may only be recognized by the host system 10–20% of the time.

Some Windows users have seen power management warnings related to this device, such as: “This device is not entering USB selective suspend state” .These warnings appear in power efficiency diagnostics but . You can safely ignore them. If you’re a power user who wants to eliminate the warning, go to Device Manager → expand “Universal Serial Bus controllers” → right‑click the “Generic USB Hub” entry → Properties → Power Management tab → uncheck “Allow the computer to turn off this device to save power.”
Because the chipset adheres strictly to the generic USB Implementers Forum (USB-IF) hub specification, . Windows Systems
