Re: Can't bring bluetooth controller up

Hi Marcel,

Hi Julio,

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:

for some reason this command is failing. That should not happen actually. What is the content of /sys/kernel/debug/usb/devices for this device.

I sent a patch to the mailing list that might fix this. Please try it out.

Thank you! I have tried the patch and my bluetooth controller works fine 
now.
