Decoding the Alphanumeric Hardware ID usb vid214b amppid7250 amprev0100 new
When you connect a hardware device, the operating system reads its device descriptor to match and load the correct driver. Here is exactly what each segment of your search term means:
is in standalone unpowered or bus-powered USB expansion docks. Brands like (e.g., the AM-UK404 model) and Ginzzu (e.g., the ) use this chip to power compact 4-port desktop splitters. 2. KVM Switches
If drivers fail to install:
The technical string typically identifies a USB 2.0 Hub Controller , often manufactured by Huada Semiconductor (formerly Jiadong) or similar generic chipset providers. In the world of hardware, this specific ID is the "fingerprint" of the uncelebrated middleman of the digital age. The Story of the Invisible Hub
A: No official driver exists because it is not needed. The generic USB hub drivers built into Windows, macOS, and Linux are the correct and only drivers required.
A new USB device signature has appeared in driver enumeration logs and hardware databases this quarter, identified by the unique pair and PID_7250 , with a revision identifier of REV_0100 . Every USB device contains a unique identifier
