M4400 Bluetooth Module Disappears/LED Stays Lit {may apply to other models}

I found that reverting the BIOS to its defaults generally fixes this problem. I've encountered it while playing music over Bluetooth speakers, and also after using the module in MacOS 10.6.

I also updated the Broadcom Bluetooth drivers to 6.2.0.9700; (available on Acer's website) I was using 6.2.0.8200, not the latest on the Dell site, which are 6.2.0.8500. Please not that there are 6.2.1.XXXX versions in the wild.

Will report back if the issue reoccurs.

Also, please note that while once upon a time, disabling and re-enabling Bluetooth in the BIOS fixed the issue, this time it did not. A full BIOS reset was required.

Working with Windows 7 x64 Pro/Ubuntu 9.10 64-bit/MacOS X 10.6.2 with 32-bit kernel and drivers but 64-bit binaries. There is no Bluetooth-enabler for 64-bit kernel, so I was unable to test this.

Downloading the drivers from the Broadcom website fails because the installer identifies the adapter as Dell's, and then asks you to download it from the OEM website.

Please let me know if any of you find a 6.2.1.XXXX version that functions on any Dell.
