Hi Gerd,
In the "USB 2.0 Quick Start" write-up you said about USB
passthrough:

> host, any device which is plugged in there gets passed to the
> guest
A customer is asking what happens if a USB hub is plugged into
the specified port (instead of a device). Will the hub get
passed through and the guest will see all devices plugged into
that hub?
Thanks,
Stuart

No. You can't pass through hubs.
cheers,
Gerd
