Yes, there is no question that Kernel mode drivers (KMDF) need to be
signed (Code Integrity Signing) on Vista 64.  It is not clear whether
User Mode drivers (UMDF) need to be signed since they are not kernel
mode drivers.  You can write USB UMDF drivers, so if they don't
require signing, this would be the way to go.

The link you posted does not say anything about UMDF.

I use libusb to talk to the QS1R Receiver, so I am interested in this
also for people who will use 64 bit Vista.
