In corporate IT environments, knowing the VID and PID allows administrators to create specific policies. For example, using Group Policy in Windows, an admin could block all devices with VID 214B to prevent employees from using unauthorized specific flash drives.
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:
PID (Product ID): This is a 16-bit number chosen by the vendor to identify a specific product model.
REV (Revision): 0100 typically refers to the device release number or firmware version. "0100" usually indicates the initial release version (version 1.0) of the hardware/firmware.
Specifically, this combination is commonly found in:
This forces Windows to use its native USB Mass Storage driver.
The REV 0100 often indicates a specific firmware version on the USB bridge chip. This particular revision is known for:
If your device is a DVD writer, corrupted filter drivers are the #1 cause. Warning: Editing the registry incorrectly can break your system.

The hardware ID USB\VID_214B&PID_7250&REV_0100 identifies a Generic USB 2.0 Hub produced by Huasheng Electronics (also associated with Ameco Technologies (Shenzhen) Co., Ltd.). This specific chipset is commonly found in budget-friendly 4-port USB hubs and multi-device switches. Device Identification
Vendor ID (VID): 214B (Huasheng Electronics / Ameco Technologies). Product ID (PID): 7250 (USB 2.0 Hub Controller). Revision (REV): 0100 (Firmware version 1.00). Chipset: Often identified as the HS8836A 4-port hub chip. Common Product Applications
This hardware ID is frequently seen in the following types of consumer electronics:
4-Port USB 2.0 Hubs: Basic unpowered or bus-powered hubs, such as those from brands like Gembird or generic models found on Temu.
USB Switches: Devices like the AIMOS AM-UK404, which allow sharing multiple USB peripherals (keyboard, mouse) between multiple computers. usb vid-214b amp-pid-7250 amp-rev-0100

Based on the hardware identifiers provided, here is the "story" of your device:
The string "USB VID_214B PID_7250 REV_0100" is the digital fingerprint of a Huasheng Electronics USB 2.0 Hub. The Identity
Vendor ID (VID) 214B: This identifies the manufacturer as Huasheng Electronics.
Product ID (PID) 7250: This specific ID is almost exclusively used for their 4-port High-Speed USB 2.0 Hub controller.
Revision (REV) 0100: This indicates the first firmware version (v1.00) of the chip. Where You’ll Find It
You aren't likely to see "Huasheng" on the box. Instead, this internal chip powers various affordable, third-party peripherals, including:
USB Switches: It is the brain inside AIMOS AM-UK404 4-in-4-out KVM switches.
Budget Hubs: It often appears in generic 4-port expansion hubs like those from GINZZU (specifically the GR-315UB model).
Embedded Systems: It is frequently used to add extra ports to Raspberry Pi setups or other small Linux-based projects. Common "Plots" (Issues)
If you are looking this up because of a technical problem, users commonly report:
Intermittent Connection: These chips can sometimes be picky with power. If it’s failing, it might show up as an "Unknown USB Device" in Windows Device Manager or fail to boot properly on a Raspberry Pi.
Speed Caps: While it claims "High-Speed," it is strictly a USB 2.0 device, meaning its maximum theoretical transfer speed is 480 Mbps. In corporate IT environments, knowing the VID and

The USB device with VID 214B, PID 7250, and REV 0100 is identified as a Huasheng Electronics USB 2.0 Hub. This hardware ID typically belongs to generic high-speed USB hubs often found in laptops (such as ASUS and HP models) or as standalone powered hubs. Device Details Vendor ID (VID) 214B: Registered to Huasheng Electronics.
Product ID (PID) 7250: Specifies the device as a USB 2.0 Hub.
Revision (REV) 0100: Indicates the firmware version is 1.00. Device Type: Generic High-Speed USB Hub. Driver Information
Because this device is a standard USB Hub, it does not require specialized third-party drivers on modern operating systems like Windows 7, 10, 11, or Linux.
Windows: Uses the native Generic USB Hub driver (usbhub.sys) provided by Microsoft.
Linux: Recognized natively by the xhci_hcd or ehci_hcd kernel modules as a "New high-speed USB device".
Update Method: If the device is not working, it is best to update via Windows Update or check your computer manufacturer’s support site, such as HP Support or ASUS Support, for chipset driver updates. Troubleshooting
