** Description changed:
OVERVIEW
Dell provides a Bluetooth module for laptops that works with Linux only
when the laptop is shipped with XP. Laptops shipped with Vista uses a
different firmware for th BT module, which isn't recognized by Linux.
DIAGNOSTICS
Even though you've remembered to enable Bluetooth support in the BIOS and/or
using the switch on your laptop,
'hcitool dev' gives no output, indicating no bluetooth adapters present.
'lsusb' only lists the ID, but provides no desciption:
Bus 001 Device 005: ID 413c:8105 Dell Computer Corp.
RELATED BUGS
For Toshiba laptops, you may have to use omnibook (bug 180659) or
toshet (bug 110202).
WORKAROUNDS
1. Boot into windows, then reboot (without turning off power) into
Linux.
2. Install Windows XP, and use Dell's DFU tool to install the XP-specific
firmware, which is availabe from:
http://support.us.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R117967&formatcnt=1&libid=0&fileid=156024
+
+ or use the Vista to XP firmware downgrade tool:

After the firmware update, the 'lsusb' command should list (among other
things):
% lsusb
:
Bus 001 Device 010: ID 413c:8103 Dell Computer Corp. Wireless 350 Bluetooth

Original bug regport:
I'm running a fresh Dapper on a Dell Inspiron 9400. There is Bluetooth
in the laptop, but the OS doesn't seem to see it, saying that no
bluetooth hardware is found.
