On most systems, you’ll see output similar to:
In its most advanced incarnation (the MW7299 chip), the device powers compact USB‑C dongles that let you charge your laptop and connect peripherals through a single port. These dongles are widely available on Amazon and AliExpress for around $20–40. The built‑in PD3.0 controller supports up to (65W or higher with external power), while the integrated BC1.2 charging ports can deliver 1.2A to charge phones and tablets even when the host computer is off or in standby.
Several Raspberry Pi users have reported that this hub is recognised only when connected to a Pi 3 or Pi 4. The system logs show the hub enumerating correctly ( New USB device found, idVendor=214b, idProduct=7250 ), but it later fails to stabilise, often with USB errors like -71 (protocol error).
Based on the hardware identifiers provided, here is the "story" of your device: usb vid-214b amp-pid-7250 amp-rev-0100

No. It is a legitimate hardware identifier. However, malware can disguise itself as a USB device. If this ID appears and you have no external device plugged in, run a full antivirus scan. If it appears only when you plug in your DVD drive, it is safe.
When operating systems like Windows or Linux query a connected USB peripheral, they pull these specific strings—known as Hardware IDs—directly from the device’s internal firmware descriptor to identify the manufacturer, the product line, and the revision number. Anatomy of the Hardware ID On most systems, you’ll see output similar to:
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:
Bus 001 Device 006: ID 214b:7250 Huasheng Electronics USB2.0 HUB
Since this ID is common in HP machines, visiting the HP Support website and searching for your specific laptop model's USB or chipset drivers is the best solution. 3. Use Driver Management Tools Several Raspberry Pi users have reported that this
For a device with the VID 214B, PID 7250, and REV 0100, finding the right drivers or software might be crucial for full functionality. Here are some steps:
One of the best features of this device is its broad, out-of-the-box compatibility across multiple operating systems.
