Troubleshooting a USB Bluetooth Dongle

Tue Nov 9 18:04:19 UTC 2010

Max, 

First, thank you so much for the work you did. After syncing
everything up, I was able to get my bluetooth dongle to work. Oddly
enough, I have to stop and then start /etc/rc.d/bluetooth to get it to
work but that may be because I didn't completely clean out my first
attempt. 

I was able to get my headset to pair : 

[tethys]:/dev> sudo
hccontrol -n ubt0hci create_connection 01:23:45:67:89:84
BD_ADDR:
01:23:45:67:89:84
Connection handle: 21
Encryption mode: Disabled [0]

hcsecd[6558]: Got PIN_Code_Request event from 'ubt0hci', remote bdaddr
01:23:45:67:89:84
hcsecd[6558]: Found matching entry, remote bdaddr
01:23:45:67:89:84, name 'AS1', PIN code exists
hcsecd[6558]: Sending
PIN_Code_Reply to 'ubt0hci' for remote bdaddr
01:23:45:67:89:84
hcsecd[6558]: Got Link_Key_Notification event from
'ubt0hci', remote bdaddr 01:23:45:67:89:84
hcsecd[6558]: Updating link
key for the entry, remote bdaddr 01:23:45:67:89:84, name 'AS1', link key
doesn't exist 

However, how do I get audio to actually output through
the headset is the question? My apologies if this is an obvious question
but I wasn't able to find much on this and in fact found threads going
back to 2005. 

Sincerely,
Rusty Nejdl

Well, that didn't quite go right:

And, you can keep the hardware and hopefully make some good use out of
it. Thanks! Rusty On Mon, 8 Nov 2010 16:59:23 -0800, Maksim Yevmenkin

download fw driver package from
http://people.freebsd.org/~emax/ath3k.tar.gz [2] this package contains
two drivers: 1) ath3k-1 -- driver to hold ath3k-1.fw image (obtained
from fedora) 2) ubtath3kfw -- fw download driver you need to build both
drivers from source. after you untar the package, please execute % make
depend % make if everything goes well, you should have .ko files in both
directories. please kldload both modules, i.e. # make -C ath3k-1/ load #
make -C ubtath3kfw/ load then you need to load ng_ubt(4) module, i.e. #
kldload ng_ubt now you should be able to attach your dongle and after
few seconds ng_ubt(4) should pick it up, i.e. i have in my

Hello, I am trying to find a working bluetooth dongle or get the one I
have working. I purchased a ASUS USB-BT211 [1] which is cheap but is
not picked up by FreeBSD. All of the bluetooth devices mentioned on the
website are not manufactured any more and I was hoping to be able to
utilize something more recent. So, if anyone can recommend a recent
device like the above or how I can assist in troubleshooting the device
I purchased, I would appreciate any feedback. i assume that you have
kldload(8)ed ng_ubt(4) driver, correct? if you did, and it still does
not work, then could you please dump usb descriptor for the device?
quick google search suggests that at least some of those adapters are
based on atheros ar3011 chip (vendor/device id 0x0cf3/0x3000) , and
require firmware download. basically, very similar to a certain broadcom
chip, for which we have ubtbcmfw(4) driver. [...] thanks for the
information Nov 2 16:08:02 tethys root: Unknown USB device: vendor
0x0cf3 product 0x3000 bus uhub8 Nov 2 16:08:02 tethys kernel: ugen3.3:

it gives you vendor/device id pair which is 0x0cf3/0x3000. in other
words, your adapter is based on atheros ar3011 chip and will require a
special (new) driver that would download firmware. ubtbcmfw(4) will not
work, because its for broadcom chip. i only mentioned this because it
would be similar, but not the same :) [...] So, any suggestions on where
to go next? 1) need to write a special ubtathfw(4) driver; 2) obtain
firmware (i assume it would be on a cd that came with the dongle); the
good thing is that linux 2.6.33.7 kernel already has firmware driver,
so, it makes it easier to port. i can probably take a stab at it, but,
without device, you would have to test it (and likely to crash your
machine several times :) are you up for it? thanks, max Max, Well, I
have 3 different options: 1) Sure, I would be happy to test. 2) I am
also testing out USB Pass through into VirtualBox and so can do some
sandbox testing there. 3) I would be happy to order one and have it sent
your way if you would like. Just let me know your address. Thanks! Rusty
