Edit Duo and DuoX simultaneously?

is this page still current?: https://wiki.moddevices.com/wiki/Custom_IP_Address

…it says there:

At this point it’s not possible to have 2 MODs connected via USB, even if they use different IPs. If you need 2 MODs, consider using one MOD connected via USB and the other connected via Bluetooth.

…so, is it true that we can’t connect both a Duo and a DuoX simultaneously to one computer via USB, for editing?

Yes that is true.

I tried several things before, but did not manage to make it work.
My knowledge of local networks is limited, plus it involves specific dnsmasq config.

If you find something that works, please let us know. But for now that is indeed the case, sadly.
