Cannot connect to any outside devices through bluetooth.
And I think this is not a bug of low level driver. Because both my
laptop and a usb bluetooth card cannot work.
Thanks,

Hi, please explain the "cannot work" in detail,
Firstly check dmesg and hciconfig to see if there's anything wrong.

Do you part is OK?
I think it will be very easy to reproduce.

does dmesg show something? I'm using a -rc kernel and bluetooth is working to
me.

I did not see your problem, my usb dongle usbid is 0a12:0001 as well,
maybe bisect is the way to go.

What dmesg shows is included above. The tell tail for this bug is the error 22 from
user space. I see nothing on the kernel side.

I can try but this bug was introduced during the .38 to rc1 window. I've not had much luck
bisecting through pre rc1...
Is there any good way to trace what is giving the 'Invalid argument 22'?

Hi, I have the same problem here. My usb blue-tooth dongle can not be enabled up
in .39 kernel series.
In 2.6.38.x and earlier it works fine.
Anny suggestions?
Thank you very much.
Best regards Milan.
