I'm running Leopard and want to use the built in bluetooth in my iMac with my XP running on Fusion. I tried plugging in a usb dongle to try to patch through to Fusion but when I went to connect hardware > USB it didn't show up (other USB mice and keyboards don't show up either, it ). I tried patching through the built in iMac bluetooth and the XP found it and tried to install it. It couldn't find the drivers for it and it failed to install. I hear you're supposed to install BootCamp drivers from the Leopard DVD. I bought this iMac after it was returned and got a discount because it was missing the Leopard disks (I plan on contacting Apple to see about getting the disk sent to me). In the meantime is there anything I can do to use my built in bluetooth with my XP in Fusion? if it helps, I'm using an 20" Aluminum iMac.
