Query: Wait a few weeks - Not compatible with Vista Ultimate

I have Vista Ultimate, all updates installed, the latest release of the wireless reciever's drivers (1.10.118.0), USB 2.0 and everything else and this unit will not work.It will however work on XP, I have a dual boot system. Which means there's nothing wrong with my hardware and that this is a big driver problem for Microsoft.And to quote another reviewer "leave it to Microsoft to release a new product that's incompatible with their latest and 'greatest' Operating System".
