Hello !
There is no problem using a thunderbolt port if you want to, as the thunderbolt is USB compliant this should works flawlessly.
Fun fact about USB speed, the device declare it's speed (and power) to the host. The host adapt itself to the device in order to speak at the same speed.
If the computer is not able to deliver the required speed or power, you will have an OS warning about that.
The MiniFuse is pretty standard and will not need anything specific, there will be no issue plugging it wherever you want (still, avoid unpowered cheap giant USB hubs).
