It's hard to tell without knowing what virt-manager is doing.

However the general thing with the arm64 virt machine is it is fairly
bare by default (compared to a PC which includes a bunch of stuff in its
default device model). As a result you need to declare all additional
devices you wish to use.

There is no particular reason why you shouldn't be able to instantiate a
virtio USB hub for your device although you would want it to be
discover-able so on a virtio-pci bus.

Can you include you current QEMU command line?
