Windows hardware IDs

Have you ever found that the OS did not find a device driver? And when there were several devices?
And then something was hanging out in the Device Manager like “unknown system device”. And how to understand what kind of device it is?

After installing the whists, I had two such devices: “unknown ethernet controller” and “unknown base device”. I had to peek into the Details-> Properties eyes. There was nothing interesting in the Device Description, but Hardware IDs were already more interesting. But why are there several?

Googling the phrase "hardware ids" came across an article , after reading which all became clear:
')
This is a hardware ID. In most cases, a device has been associated with a list of hardware IDs. (However, there are exceptions - see Identifiers for 1394 Devices). It should be noted that the device will be free of charge.

In turn, in the process of searching for my ethernet controller by device id, it turned out that I did not have an Intel PRO / Wireless 2200BG, but hp w400 on an Atheros chip .:)

Like this. Sorry if you discovered America.
