Usb controllers

Hello all

I’m running HA on an hp elitebook. which only has 2 usb ports.

One port is for the mouse and keyboard and on the other port i connected the aeotec USB.and all works fine.

next month i will be expanding my automation substantially (at least in my mind) .

part of the expansion will include installing a ZigBee TRV for all my radiators.

To support this I will need to purchase a ZigBee usb controller
my questions:
can i install the ZigBee usb and the z-wave usb on an USB expansion board without any
interference between both usb?

will i need to re install and pair all my z wave devices again?

the Nortek HUSZBZ will not work with European z wave frequencies

thank you
