Understanding the USB Hardware ID: VID-214B PID-7250 REV-0100
If you have encountered the hardware identifier USB\VID_214B&PID_7250&REV_0100 in your Windows Device Manager or system logs, you are likely looking at a High-Speed USB 2.0 Hub. This specific hardware ID is commonly associated with internal or external hub controllers, such as those found in laptop chassis, KVM switches, and multiport expansion docks. Device Identification and Manufacturer
Vendor ID (VID): 214b – 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.
Product ID (PID): 7250 – This identifies the specific product as a USB 2.0 Hub. Many community reports suggest this PID specifically refers to the HS8836A 4-port hub chip.
Revision (REV): 0100 – This indicates the firmware or hardware revision version 1.00. Where You’ll Find This Hardware usb vid-214b amp-pid-7250 amp-rev-0100
This hardware ID is frequently spotted in the following devices:
External USB Hubs: Brands like GINZZU (e.g., GR-315UB) often use this controller for their 4-port hubs.
USB Switches/KVMs: The AIMOS AM-UK404 4-in 4-out USB switch is a prominent example of a device utilizing this VID/PID combination.
Internal Laptop Hubs: It is often found pre-installed in laptops from major manufacturers like ASUS and HP, where it manages internal connections for webcams, card readers, or external USB ports. Driver Requirements
For most modern operating systems, including Windows 10, Windows 11, and Linux, no manual driver download is required.
Standard Class Driver: Because the device identifies as a "Generic USB Hub," it uses the built-in standard USB hub driver provided by the operating system.
Automatic Installation: In Windows, it should appear under "Universal Serial Bus controllers" as a "Generic USB Hub" or "USB2.0 HUB". Troubleshooting Connectivity Issues
If you see this ID with a yellow exclamation mark in Device Manager (e.g., "Unknown USB Device (Device Descriptor Request Failed)"), consider these steps:
Power Supply: If using an external hub, ensure it has enough power. Some 4-port hubs struggle with high-draw devices like external hard drives.
Cable Integrity: Intermittent recognition (a common issue with this specific hub ID) is often caused by poor-quality USB cables or loose connections.
Controller Reset: In Device Manager, right-click the "Generic USB Hub" with this ID, select Uninstall Device, and then restart your computer to force Windows to reinstall the standard driver.
