If you are looking this up because of a technical problem, users commonly report:

Sometimes, Windows 10/11 fails to pull the correct driver from its repository.

If your system log ( dmesg ) outputs intermittent errors for device 214b:7250 , you can force the Linux USB module to use an alternative initialization cadence: 7250 - USB Devices

Specifically identifies the HS8836A 4-port hub controller chip. usb vid-214b amp-pid-7250 amp-rev-0100

The controller behind this ID operates under the standard Universal Serial Bus specifications for mid-tier extension hubs. Specification USB 2.0 High-Speed (Up to 480 Mbps) Power Draw 100mA to 500mA baseline Host Driver Native OS Generic USB Hub Driver ( usbhub.sys ) Topology 4-Port or 7-Port downstream configurations Common Issues and Troubleshooting

This article explores the technical significance of these identifiers, how to interpret them, and why they matter for troubleshooting and hardware compatibility.

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. If you are looking this up because of

Specifies the precise product silicon architecture or controller stepping chip.

If this device is waking your computer from sleep unexpectedly:

: Users have reported that hubs with this ID may only deliver USB 2.0 data throughput even when connected to USB 3.0 ports. Power Stability Specification USB 2

0x214B Product ID (PID): 0x7250 Revision: 0100

This Windows error implies that the OS detects physical hardware but cannot pull the complete VID_214B&PID_7250 string.

The four physical pins inside a USB-A port (VCC, GND, D+, D-) can wear down. If the data channels (D+ and D-) lose complete connection while the power pins (VCC and GND) remain operational, the PC will receive electrical current but fail to pull down the device descriptor packet.
