[Bug 37288] Re: Bluetooth not discovered on Dell Inspiron 9400

[Ketil Malde]

I have a Dell Latitude D620, which included (according to the "Compatible systems" link at the bottom of http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R129472&SystemID=LATITUDE%20D620&servicetag=&os=WW1&osl=en&deviceid=7388&devlib=0&typecnt=0&vercnt=2&catid=-1&impid=-1&formatcnt=1&libid=5&fileid=172476
) a Dell 350 Bluetooth module.

BT is enabled in the BIOS, and the BT LED on my computer is shining
happily.

However: 'hciconfig' gives no output, 'hcitool dev' shows only the
'Devices:' header, and 'hcitool scan' tells me that "Device is not
available: No such device".   However, the BT device shows up on the USB
bus, 'lsusb' tells me:

   Bus 001 Device 005: ID 413c:8105 Dell Computer Corp.

Apparently, this can be caused by a Vista-specific firmware "upgrade"
from Dell that sabotages the BT module, see

Like the participant in that thread, I no longer have Vista or XP installed.  I tried to download the Windows driver from Dell to download it with dfutool http://www.holtmann.org/linux/bluetooth/dfu.html.  The file, R129472.EXE, can be 'unzip'ped to 
BtSwSP2.exe, which 'cabextract' can decompose into a set of DLLs and such.  I'm not sure how to proceed from there, though.

(dfutool is not packaged with bluez-utils in Ubuntu, should I file that
as a separate feature request/bug?)
