    Re: 9.10 "Bluetooth is disabled" Dell M90

    I foraged once again through google and the various forums. One solution that might work is installing XP on another partition, running a small Dell utility which fiddles with the Bluetooth Adapter's firmware and checking back to see if it works in Ubuntu. This solution is far from ideal and takes away from the whole point of installing Ubuntu in the first place. I may attempt it as a final solution but in the meanwhile here is some more information to help debug the problem:

    Code:
    $ lsusb | grep -i blue
    Bus 001 Device 005: ID 413c:8126 Dell Computer Corp. Wireless 355 Bluetooth

    My main concern has now shifted to why the device hci0 can't be initiated. If we can get 'hcitoo dev' to show the device which clearly exists under 'lsusb' we will have made definite progress.

    For those who think this may be have something to do with the Kernel here is the list of modules attached:

    PROBLEM SOLVED

    The solution was updating the BIOS from Version A03 to A10 on my Dell Inspiron E1705.

    Unfortutnately I had already gone through the hassle of installing Windows XP on a Partition and was updating the drivers for it from support.dell.com when I ran across the BIOS update utility. Running it before even installing the Bluetooth Driver in XP fixed the Bluetooth issue on Ubuntu. So the problem was in the BIOS to begin with.

    I googled for Ubuntu BIOS updates and there are a couple of ways of updating Dell BIOS from within Ubuntu so I would recommend using those avenues for updating BIOS before trying more esoteric solutions for this problem.
