What is the best way to investigate an unfamiliar HID device ..?

Question

Iron

There is some abstract device "a set of light bulbs / buttons with a USB tail" and is defined as HID.
Watching the activity with an oscilloscope while pressing the buttons, I believe that this device sends reports.
The question is, how would I investigate this device, maybe there is some kind of program, or in Linux can I somehow force the data from the device's HID to be poured into a file / console?
As you can see from the wording of my question, I'm not at all strong in the subject yet, just before smoking mana on HIDs, I would like to make sure that the device really transmits what I need, and not some kind of status like battery charge ...

Answer 1

if it is defined as HID and Xs are running: you can try to look at the keycodes using xev, and then you can rebind them to some key combinations.

Answer 2

Under Windows, there are definitely sniffer programs. Unfortunately, I don’t remember the name anymore, but 6 years ago, Apple reversed the monitor in the same way to determine which touch buttons on it are touched.

Answer 3

Try to use this thing: USB analyzer circuit on the site ra4nal.qrz.ru/index.shtml

Answer 4

Maybe it's worth building a kernel with debugging enabled for hid devices and looking at the logs?
