Indicates the firmware or hardware engineering iteration (v1.00) of the controller silicon. Where Is This Hardware Used?
You aren't likely to see "Huasheng" on the box. Instead, this internal chip powers various affordable, third-party peripherals, including:
Additionally, these IDs help identify "fake" drives. Fraudulent sellers sometimes program cheap, low-capacity drives to report a higher capacity to the OS. If a supposed "1TB drive" reports a VID/PID combination associated with a cheap 8GB controller model, it is an immediate red flag.
To verify if the hardware is physically alive on a Linux system, run: lsusb -d 214b:7250 -v This command will output the Endpoint Descriptors usb vid-214b amp-pid-7250 amp-rev-0100
: Represents firmware version 1.00 , informing the operating system of the exact silicon revision layout. Technical Specifications
Before diving into fixes, it is crucial to understand what this hardware signature represents. Vendor ID (VID) 214B: Identifies the manufacturer as Huayi Electronics Co., Ltd. (or associated generic Chinese manufacturers like Product ID (PID) 7250: Identifies the specific model, usually a USB 2.0 Hub Multi-Slot Card Reader Controller Revision (REV) 0100:
The string refers to specific identifiers for a USB device. Indicates the firmware or hardware engineering iteration (v1
If you are trying to configure this hardware on a specific operating system, let me know you are using so I can tailor the commands. What physical device (hub, mouse, keyboard, or adapter) are you attempting to connect? Share public link
The REV 0100 often indicates a specific firmware version on the USB bridge chip. This particular revision is known for:
Locate the device, right-click it, and select . Choose Browse my computer for drivers . To verify if the hardware is physically alive
Device functions on rear motherboard ports but fails on front panel
Windows logs every USB initialization. If a flash drive or hub with the VID_214B identifier is abruptly unplugged during a write operation, the cached operating system registry values become corrupt. The OS will subsequently fail to parse the Hardware ID on subsequent insertions. 2. Underpowered USB Control Line
