Hi,

I have a card reader with bluetooth controller built-in (Broadcom 
BCM2045A) and it stopped working suddenly some days ago as it appears 
down and I can't bring it up with hciconfig, this is what happens:

sudo hciconfig hci0 up
Can't init device hci0: Operation not supported (95)

This is the output of hcidump when running this command:

I have looked on rfkill and everything seems correct and the LED is lit, 
I'm using Arch Linux 4.2.3 kernel.
It still works on Windows, so I'm lost here, is the device faulty or 
something?

Thanks in advance,
