After extensive cross-referencing with USB ID repositories ( linux-usb.org , devicehunt.com , and vendor lists), the device identified by is:
Because VID 214B is generic, some cheap adapters misuse this PID. To verify authenticity:
The string vid-214b amp-pid-7250 amp-rev-0100 is essentially a parsed version of a standard USB descriptor. The amp segments in the string are actually an artifact of how some software parses the ampersand symbol ( & ) used in hardware IDs. Therefore, the string technically translates to: usb vid-214b amp-pid-7250 amp-rev-0100
To the average user, this string looks like gibberish. However, to a system administrator or a hardware enthusiast, it is a digital fingerprint. This article will break down this specific identifier, explain what it tells us about the connected hardware, discuss the importance of Vendor and Product IDs, and provide a guide on how to troubleshoot devices associated with this string.
USB hub only recognised intermittently - Raspberry Pi Forums After extensive cross-referencing with USB ID repositories (
Searching for typically means you are either troubleshooting a driver issue, identifying an unknown USB device, or developing embedded systems. Understanding that this ID points to a CH340-based USB-to-UART bridge saves hours of detective work.
Before identifying the device, let’s decode the anatomy of this string: Therefore, the string technically translates to: To the
These adapters are ubiquitous in the maker and electronics community. They are commonly found in:
If you have an old 2.5-inch or 3.5-inch IDE hard drive from a vintage Windows 98 or XP machine, and you plug it into a modern PC via a USB adapter, there’s a high chance this is the chip doing the translation.
