Description Andrew Cagney 2005-04-06 14:45:11 UTC
(is this a kernel, doco, anaconda, or ... bug?)

The DBT-120 adaptor doesn't work out-of-the-box.  The driver reports;

bcm203x_probe: Mini driver request failed
bcm203x: probe of 1-1:1.0 failed with error -5

You need to fetch the firmware from:

and install the files:

BCM2033-MD.hex BCM2033-FW.bin

in /lib/firmware (the firmware tar ball will do it if you do: ./configure; make;
make install).

Comment 1 Colin Charles 2005-04-07 05:37:51 UTC
FWIW, tried it on Rawhide/x86 (its almost FC4test2 now)
Bluetooth: Core ver 2.7
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: HCI USB driver ver 2.8
usbcore: registered new driver hci_usb

And it worked. I recall this working with Rawhide (pre-fc4t1) on powerpc as
well, however I haven't rolled an install out in a while (and am away from my
ppc boxes now)

lsusb reports the adapter (a dbt-120) as:
Bus 003 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle
(HCI mode)

IIRC, on irc, you reported your lsusb output as being:
<cagney> Bus 001 Device 002: ID 0a5c:2033 Broadcom Corp. BCM2033 Bluetooth

So guess this isn't the first time they release the same product model and
change the internals of it with a different manufacturer..

Comment 2 Andrew Cagney 2005-04-07 16:40:14 UTC
PS: The above, while correct, isn't working.

(Following DWMW2's pointer) I'm fi that /etc/hotplug/firmware.agent fails with:

+ cp /lib/firmware/BCM2033-MD.hex /sys//class/firmware/1-1/data
cp: cannot create regular file `/sys//class/firmware/1-1/data': No such file or
+ echo 0
/etc/hotplug/firmware.agent: line 49: /sys//class/firmware/1-1/loading: No such
file or directory

could you try:

Comment 5 Harald Hoyer 2005-04-11 16:03:01 UTC
needs udev-056 and 2.6.12 or patch for 2.6.11

Comment 7 Ziga Mahkovec 2005-04-12 13:51:11 UTC
I've also been having issues with firmware loading (ipw2100) and it turned out
to be a problem with the initial event timeout in udevd:

This too is fixed in udev-056, but doesn't require the kernel patch.  So if
firmware loading only fails during boot, it's likely a startup timeout issue. 
The kernel patch avoids the issue completely by allowing firmware events to
bypass the udevd queue.

Comment 8 Andrew Cagney 2005-04-12 14:56:39 UTC

Should 2.6.11-1.1236_FC4 and udev-050-10 work (it doesn't appear to) or do I
also need to also build / install the udev-056 rpm?

Comment 9 Harald Hoyer 2005-04-12 15:28:04 UTC
Andrew, my name is Harald and please test udev-056.

Comment 10 Andrew Cagney 2005-04-12 22:29:37 UTC
Ok, I've tested udev-056-1 and finally get:
