Thanks for the details and cautions!
I had budgeted last year for the 480 "Plain" or whatever they want to call it, and was somewhat surprised they pitched the "Ultimate" instead.

I am looking for a way to capture, analyze, and time USB traffic for a few specific cases - measurement, not design.

Anybody using a Beagle 12 or 480 with Teensy as HID? Pros and cons?

My use...

... and the IDE let's me do that even w/o a Teensy LC attached :)

Just ordered mine yesterday. Thanks!

That is cool. This works for both of these I assume?

You know, that is not a bad idea at all!

Can't find any explicit confirmation that LC has USB Raw HID and HID

That's useful for part of my needs, thanks!

But it does not cover all uses cases :(

Yeah, I wasn't expecting castellated solder. Not cutting Teensy edges like some have tried?

Trying to figure out some basics about cost, robustness, maintenance, repair in case of deploying hundreds of Teensy boards, to rack mounts.

There are two possible approaches:

If anybody has numbers already for
a) using Ethernet (with the OSH adapter) (target rate 1kHz UDP packets)
b) using USB HID RAW over PJRC Host adapter cable (also 1kHz rate)

I'd much appreciate...

Space is not the problem.
The problem I started with was having to use separate hub boxes etc. or a custom shield/breakout in the first place.

I am basically trying to make sure there is no...

Yeah, this

Thanks guys!

Yep, up to 3 concurrent physical USB connections, several use cases, e.g.

I am facing a situation where I need the on-board micro-USB of the Teensy for other purposes, but don't want to lose the ability to connect to PC, including for dev/debug over COM.

Some updates:

I'd like to try to set up - with a Teensy, if that's sensible - a fixed function "HID-over-UDP/IP" device like this:

a) fixed IP
b) receive (one-way) UDP/IP traffic on a single fixed port
c)...
