: Integrated into keyboards, monitors, or other composite devices to provide additional ports. Driver Information
It is possible that the hardware itself is failing. REV-0100 is an older chip. Try these final checks:
When connected to a computer, the device provides , each capable of simultaneous communication at different speeds. You can connect a mouse (Low‑Speed), a keyboard (Full‑Speed), and a USB flash drive (High‑Speed) at the same time without conflict. Most generic 4‑port hubs based on the HS8836A chip—such as the iSoul ultra‑slim hub or the Maxxter ACT-HUB2-4P —use this exact VID/PID. usb vid-214b amp-pid-7250 amp-rev-0100
If you are experiencing issues with a device identified by the USB VID-214B&PID-7250&REV-0100, try the following troubleshooting steps:
Windows failed to load the appropriate driver for the integrated USB hub.
Absolutely not. There is no official signed driver from Huaxu for this chip because Microsoft includes the driver already. Driver download sites often bundle adware or ransomware. Uninstall any such software immediately. Locate the device, right-click it, and select
If the peripheral is a budget flash storage unit built on this controller, its firmware loop can crash. This forces the controller chip into a read-only safety mode or a generic state where the OS can see the hardware string but cannot interact with the underlying file system. 4. Physically Damaged Contact Traces
This integrated circuit is a generic, cost-effective silicon block embedded inside dozens of consumer electronics accessories. You will typically find it driving the functionality of: External standalone multi-port USB hubs. USB switches or KVM switches (such as the AIMOS AM-UK404 4x4 switch).
. 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: Driver Information It is possible that the hardware
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.
Registered to Huasheng Electronics (sometimes indexed under parent or alternative trade names like AMECO Technologies Shenzhen). The USB Implementers Forum (USB-IF) issues this 16-bit hex code to verify the legal manufacturer.
If your USB ports are not working correctly, you will need to update or reinstall the driver for USB\VID_214B&PID_7250 . 1. Update Drivers via Device Manager Right-click the Start button and select .
If you ever see a yellow exclamation mark, you can force Windows to reinstall the driver through Device Manager: right‑click the device → → Search automatically for drivers .
