Comment 6 for bug 156133

OK. Picking this up again as it's not working again - not quite sure when it broke.

The driver for the bluetooth thumb is bcm203x. When booting I get this (dmesg | grep bcm)

[ 12.981820] bcm203x_probe: Mini driver request failed
[ 12.981831] bcm203x: probe of 1-2:1.0 failed with error -5

Strings on the binary driver reveals these interesting strings:

firmware=BCM2033-FW.bin
firmware=BCM2033-MD.hex

I have some files _almost_ named that:

# locate BCM2033-FW
(nothing)
# locate bcm2033-fw
/lib/firmware/bcm2033-fw.bin
# locate bcm2033-md
/lib/firmware/bcm2033-md.bin
# dpkg -S /lib/firmware/bcm2033-md.bin /lib/firmware/bcm2033-fw.bin
linux-firmware: /lib/firmware/bcm2033-md.bin
linux-firmware: /lib/firmware/bcm2033-fw.bin
# dpkg -l | grep restricted-modules-2.6.27-9
ii linux-restricted-modules-2.6.27-9-generic 2.6.27-9.13 Non-free Linux kernel modules for version 2.

So yes, we can rule out the restricted-modules package as source for this firmware.

# apt-cache policy linux-firmware
linux-firmware:
  Installed: 1.2
  Candidate: 1.2
  Version table:
 *** 1.2 0
        500 http://no.archive.ubuntu.com intrepid/main Packages
        100 /var/lib/dpkg/status

That's good then.

Hum, the casing...

# cd /lib/firmware/
# ln -s bcm2033-fw.bin BCM2033-FW.bin
# less bcm2033-md.bin
(The file looks like it's hex code)
# ln -s bcm2033-md.bin BCM2033-MD.hex
# modprobe -rv bcm203x
rmmod /lib/modules/2.6.27-9-generic/kernel/drivers/bluetooth/bcm203x.ko
# modprobe -v bcm203x
insmod /lib/modules/2.6.27-9-generic/kernel/drivers/bluetooth/bcm203x.ko

We seem to have a winner! Looks like there is a packaging problem in linux-firmware - modifying the package name for this bug. Hope the right people will get time to fix this.
