Hi,
I am running a 2.6.26.4 kernel with Fedora 9, with the following bluez packages installed:
bluez-hcidump-1.41-1.fc9.i386
bluez-libs-devel-3.35-1.fc9.i386
bluez-utils-3.35-3.fc9.i386
bluez-utils-alsa-3.35-3.fc9.i386
bluez-utils-gstreamer-3.35-3.fc9.i386
bluez-gnome-0.26-1.fc9.i386
bluez-libs-3.35-1.fc9.i386
I also have a USB BT dongle, and I am unable to persuade this dongle to pair with my A2DP speakers. This is what bluez tells me about the speakers:

This is what I can tell about the dongle itself:

What is happening is that every attempt to connect to these speakers is being dropped before I have a chance to authenticate with my PIN. This is the output from hcidump for a connection attempt:

It looks like these speakers don't like my dongle for some reason, but I have no idea why. The dongle is advertised as supporting BT v2.0 with EDR. I have also successfully paired these speakers with my laptop and its built-in BT support, and have also paired this dongle with my mobile phone and transferred files across to my desktop.
Can anyone see anything which might explain what is happening, please? Or maybe suggest a means of debugging this further?
Thanks for any assistance,
Cheers,
Chris
