I asked TE Support about the hub possibilities for the tx-6 and they responded this:
hi Arne,
thank you for contacting us!
yes! (Hub is compatible with tx-6) as long as the hub is powered;
we don’t recommend any specific one, as long as you ha e the chance to power it! we successfully tested this one, and when powered, it works perfectly! but we recommend you do a bit of research and find the one that fits your needs.
