I had a Boot Camp partition with Windows 7 on my 2008-era MacBook Pro, and everything worked fine.
I have a new MacBook Pro. I partitioned it using the Boot Camp Assistant, and then I copied my old Boot Camp partition using Winclone. After booting into Windows on the new Mac, I ran the Boot Camp Windows Support stuff, which supposedly installed current drivers. Almost everything works fine: I have the hi-res display, trackpad works fine, sound works fine, etc.
However, Bluetooth isn't working at all. When I try to add a device, no Bluetooth devices appear in the list. In Device Manager, the "Apple Broadcom Built-in Bluetooth" icon has a yellow warning triangle on it.
I tried uninstalling that driver and then re-running the Boot Camp Windows Support setup, but I'm back to the same situation.
Any suggestions? (Other than reinstalling Windows and all my Windows applications from scratch.)
