Output of lsusb
Dell XPS420 Bluetooth adapter not recognized by Fedora.
It is part of CAB-200 which I believe is a TEAC RU730. It's a 15 and 1 card reader plus bluetooth. The Bluetooth Manager for Gnome reports no bluetooth adaptors present. Oddly the adaptor has been recognized twice.
When I originally purchased the computer I removed the CAB-200 as I didn't think I had a need for it. When I decided to reinstall it, it was recognized by Fedora and I was able to pair a mouse. After rebooting it has never been recognized again until..
One other time I updated the firmware when booted from my Windows partition and after I rebooted into Fedora, it was recognized again and it worked with the mouse I paired originally. But again after rebooting it has not been recognized since.
It is recognized everytime without issue in Windows Vista and XP.

Output of dmesg
It's possible Bug 512347 is related but I am not sure.
This is definitely a kernel issue. If the kernel doesn't see the Bluetooth device, then user-space can't control it.

Output of lsusb after installing SoundBlaster
I disabled my motherboard audio device and installed a SoundBlasted Audigy 2 ZS. Since doing that, my Bluetooth module is recognized and working under Fedora 11 without issue.
This is also working under Fedora 12 x86_64 as well.
The main difference between the 2 logs are the kernel version, and possibly the VBoxNetAdp module being present when it works.
Remove all the third-party kernel modules junk, and try again with your original installation, it might work.
See comment 7 and 8. You can close this bug as I can no longer reproduce the issue.
