Until now I didn't realize how important this bit of advice really was! 
I use virt-manager to manage my KVM guests and had added the USB 
controller as "default". The only alternative was "USB 2". I expected 
that both were the doing the same. This is not the case however. As soon 
as I changed the USB controller of the guest from "default" to "USB 2", 
USB redirection started to work (this is with a Windows 7 guest).

Perhaps the default for the USB controller in virt-manager should be 
changed from "default" to "USB 2"? Hmmm... :-)
