KVM & USB Hasp keys

I have runnig KVM on ubuntu2.6.31-19-generic #56-Ubuntu SMP Thu Jan 28 02:39:34 UTC 2010 x86_64 GNU/Linux.
Guest system Windows 2008 Server.
Host system have two USB hasp keys

Bus 006 Device 003: ID 14a8:0001
Bus 006 Device 002: ID 14a8:0001

But they have the same Vendor and Device ID. And KVM passthrough only one key. But I need complitly two keys in guest system. How can I do this?
