USB discovery entries for Z-Wave JS are too generic

The problem

in /homeassistant/generated/usb.py there are some entries for VID/PID combo’s that identify USB dongles with a specific integration.

For Z-Wave JS this is included in the file:

{
        "domain": "zwave_js",
        "vid": "10C4",
        "pid": "EA60"
}

The VID:10C4 and PID:EA60 belong to a very generic cp210x chipset by Silicon labs. The problem is that all other devices that aren’t Z-Wave JS radio’s now show up as Z-Wave.

I’m sure this isn’t a problem for the current core integrations as Z-Wave JS and ZHA are about the only onces that use USB, but if you’d use any other dongles from a custom integration this will become very confusing for users. Also for future proofing purposes, it might be useful to identify more devices with this chipset within core.

One solution could be to identify based on description (iProduct) too just like ZHA but i’m not sure if those are provided with the Z-Wave sticks.

Additional information

^ not a z-wave dongle but is identified as one.

I think the problem is well understood, we are just waiting for vendors to provide identifiers at this point.

Even those current vendors might want to bring out different sticks in the future (e.g. Matter, etc.) with the same SiLabs chip on-board. It’s just weird to assume that a CP210x UART bridge is a Zwave device.
