I just updated Bootcamp assitant (beta 1.4). I have never been able to use my wireless mouse/keyboard on the Windows XP side. Fairly new iMac I got last Sept. Went through all of the steps posted in Bootcamp asstant. While installing the bluetooth devices I used the selection "choose a passkey for me" as advised. Later the devices said "no passcode" enabled. I thought apple had worked out the bugs on this one. Frustrating that one year later and I'm still unable to use my wireless devices on the Windows side. Bootcamp/Windows works fine with a wired keyboard/mouse. This is good because I need Windows for my work applications.

Any suggestions on a real fix?

Thanks!
