KDE does not find bluetooth adapter

I am running slackware-current on a Apple Inc. Macmini2,1. I am not running a full install an since a while (I think since 20150422) KDE Bluetooth Integration does not find my bluetooth adapter:

Code:

No Bluetooth adapter have been found.

Code:

Code:

# hcitool dev

        RX bytes:1020 acl:0 sco:0 events:46 errors:0
        TX bytes:445 acl:0 sco:0 commands:45 errors:0

I am using an Apple Magicmouse and an Apple wireless keyboard but lately the devices stop working and the computer freezes completely! I don't know why this is happening and I need help troubleshooting the problem.

I used to be able to manage the devices using KDE. I can still search the devices with

Code:

hcitool scan

or

Code:

hidd --search

. Connecting them using the command line is no problem either but after a while the computer freezes!

Code:

# rfkill list
0: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

I don't know what to do next and need your expertise.

You're probably going to need to post more information... like dmesg output and have you run dbus-monitor too see what's being said to BlueZ, etc. Are the time intervals long enough for the devices to enter a low power or sleep mode? etc.

Have you tried this?

Code:

sudo /etc/rc.d/rc.bluetooth restart

Yes, I already restarted bluetoothd using:

Code:

/etc/rc.d/rc.bluetooth restart

I never used dbus-monitor before. I played around a little bit but I don't get how I have to interpret it.

The system freeze (system does not respond at all anymore) happens at a random interval. Sometimes I am still typing when it happens, so i think the diveces do not fall into a sleeping state.

I attached 4 files (dmesg01r.log <-> dbus01r.lgo, dmesg02r.log <-> dubs02r.log). The 01-files are from the first crash and the 02 from the second.

Thanks for your help.
