All,

I recently ran "dfutool archive foo" on my IBM bluetooth adapter
(Broadcom) thinking it would save my firmware to the file "foo".  It
created a zero-length file, said that the operation timed out, and
exited.  Ever since, by bluetooth adapter has been stuck in DFU mode:

# dfutool archive foo
Available devices with DFU support:

         1) Bus 003 Device 034: ID 0a5c:2000 Interface 0 (DFU mode)

Select device (abort with 0): 1

Firmware upload ...
Can't upload next block: Connection timed out (110)

from dmesg:
usb 3-1: Product: Broadcom Bluetooth Download Device

Does anyone know why it did that and how to get the adapter out of DFU
mode?  I don't want to have to buy a new adapter...  :)

Thanks.

Jarom Hatch

if it is Broadcom then it will fail. And it is possible to get this back
out of the mode, but no tool supports it. Or maybe the dfu-util from the
OpenMoko project.
