Identifies the specific USB 2.0 Hub controller.
If you encounter an unrecognised USB device, you can cross‑reference its VID/PID in this database (or on Linux, simply run lsusb ). The repository is open for anyone to contribute new device names, helping the entire community identify hardware more easily.
If the internal driver state is corrupted, Windows needs to completely rebuild the device stack.
If Windows or macOS outputs a Code 43, Code 10, or an unassigned device error while reading this ID string, the failure stems from one of four primary issues: 1. Corrupted USB Stack Registry
To understand the device behind the code, we must first break down the nomenclature. A USB device is identified by a hierarchy of numbers reported to the host controller: usb vid-214b amp-pid-7250 amp-rev-0100
If you need this post for a different platform (e.g., Reddit, Twitter, GitHub issue) or a different tone (shorter, more technical, or troubleshooting-focused), let me know and I’ll adjust it.
Registered to Huasheng Electronics (often utilizing underlying controller chips from associated fabless semiconductor brands like HuaYi).
Note down the revealed by the tool (e.g., HY6919 or similar variations).
You almost never need to download a separate driver from the manufacturer. However, if you’re using a specific device like the AIMOS AM‑UK404 that has extra switching logic, check the manufacturer’s website for any optional utility software. Identifies the specific USB 2
Indicates version 1.00 of the firmware or hardware implementation. Functional Breakdown
) or standard Linux hub drivers. If the device is not working: Power Cycle:
. 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:
In most cases, . The problem is Windows failing to assign the built-in driver correctly. If the internal driver state is corrupted, Windows
(e.g., Code 10, Code 28) you see in Device Manager. Your laptop model (e.g., HP 14-dq1xxx). Is this an internal hub or an external one?
When a computer fails to recognize this string properly, it usually flags the device as an or drops the peripheral entirely. Deconstructing the Hardware ID
This article provides a comprehensive guide to understanding what this device is, why driver issues occur, and how to successfully install the necessary drivers. What is USB\VID_214B&PID_7250&REV_0100?
