Hello,

My new WLAN mini PCI card has arrived and is installed into my laptop.

I hope this at least fixes the unstable WLAN but unfortunately Bluetooth keeps absent.

While searching, I've found something that may be interesting:

Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: Product: Bluetooth USB Host Controller
Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: Manufacturer: Atheros Communications
Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: SerialNumber: Alaska Day 2006
...
Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: USB disconnect, device number 3

So yes, on this card the bluetooth controller is connected via USB. I just cant see it in lsusb as it, for some reason, disconnects itself. I have no idea what is causing this...

Maybe I should just stick with my USB dongle. Linux and MiniPCI Bluetooth doesn't seem to be a good combination.

Manuel
