Version information: bluez-hcidump-1.37, bluez-libs-3.12, bluez-utils-3.12

Any idea what could be the problem?

Thanks for your help.

Maybe you have to pair with the device first?

[Nb You obviously know much more about the subject than me,
so this is probably nonsense!]

Probably not relevant, but with Fedora-7
I also seem to need bluez-gnome , though I use KDE.

Hi Timothy

`hcitool cc 00:0D:44:5D:1A:9B` also fails.

I feel that the problem lies somewhere else. Let's see. Hopefully someone 
can drop a hint. BTW, I'm not really deeply familiar with the bluetooth 
architecture I have to admit.


Best wishes
