Voltage sag or high resistance across internal chassis wires Connect device directly to the back of the motherboard

The device is a standard USB 2.0 hub, a tool designed to expand a single USB port into multiple ports. Here are its core specs:

Some Windows users have seen power management warnings related to this device, such as: “This device is not entering USB selective suspend state” .These warnings appear in power efficiency diagnostics but . You can safely ignore them. If you’re a power user who wants to eliminate the warning, go to Device Manager → expand “Universal Serial Bus controllers” → right‑click the “Generic USB Hub” entry → Properties → Power Management tab → uncheck “Allow the computer to turn off this device to save power.” usb vid-214b amp-pid-7250 amp-rev-0100

If you have docked or undocked a laptop (like an HP 14-dq1xxx), the system might be scanning for the connected hub components. How to Fix USB\VID_214B&PID_7250 Driver Issues

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 Voltage sag or high resistance across internal chassis

But what does it actually mean, and why should you care? This article will decode every part of that identifier, tell you exactly what hardware it represents, explain how to find drivers (if you need any), and walk you through real-world use cases and troubleshooting. By the end, you’ll know more about this little string of text than 99% of computer users.

This represents the Revision number of the hardware (Revision 0100). If you’re a power user who wants to

Want to confirm that you have this device on your own computer? Here’s how:

Basic unpowered or bus-powered hubs, such as those from brands like Gembird or generic models found on Temu.

If external hard drives, webcams, or capture cards cut out randomly during data transfer, the issue is typically rather than hardware damage. Because unpowered VID_214B hubs share a static 500mA budget from the computer's host port, connecting more than one high-draw peripheral causes the controller chip to temporarily shut down to prevent overcurrent loops.

USB hubs can get stuck in an un-responsive logic loop due to minor static or power surges. Unplug the USB device entirely from the computer. Shut down your computer.
