[Solved] Can't Get Bluetooth Adapter To Run

Hello all,
I have a notebook (Dell Studio 1555) with an internal bluetooth adapter (dell 370, if I remember correctly), that I'm unable to set up in Gnome 3.10.
It has worked before under KDE 4.10, but I think it stopped working under KDE 4.11, prior to switching to Gnome, though I'm not sure.
Here are some outputs I'm getting:

Re: [Solved] Can't Get Bluetooth Adapter To Run

Hi adam,

I'm running 64bit Arch on a Studio 1557 with an integrated usb bluetooth adapter (BCM2046).
In 2011 I had the very same problem you describe and got it fixed. Let me explain:

The bluetooth adapter has 2 modes of operation: HID mode and HCI mode.
In HID mode, it presents itself as a keyboard/mouse input device (in your case 413c:815[8/7]).
This allows you to use e.g. a bluetooth mouse that has been paired earlier - even if your OS doesn't support bluetooth.
In HCI mode, the device presents itself as a regular bluetooth adapter which can be used by your bluetooth stack (e.g. bluez) - that's what we want.

The problem back in 2011 was, that my adapter would default to HID mode and to switch it to HCI mode I had to use the 'hid2hci' tool (now part of bluez-utils).
For some time now bluez ships a udev rule which takes care of switching modes so everything worked flawlessly.
A couple of weeks ago, however, the problem resurfaced and I haven't found a fix yet.
I noticed that the udev rule isn't triggered anymore and running hid2hci (/lib/udev/hid2hci) manually doesn't work either (gives an error saying 'unable to handle [devpath]').

The only way to use the bluetooth adapter in arch for me is to boot Windows inside a Virtual machine, attach the USB touchpad device (the HID proxy) and let Windows switch it to HCI mode.
This, however, only lasts until I reboot/resume from standby.

I believe this regression was caused by a package upgrade, since an older arch installation I had lying around still recogniced the adapter while an up-to-date installation wouldn't.

Unfortunately, said lecacy installation is now gone and downgrading arch to a point before the regression doesn't seem feasible.

Any suggestions are more than welcome!

So long,

rev

Thanks for the pointers, ijanos and revinary.
I tried hid2hci but could not get it to work either.
I'll post again if something changes.

Re: [Solved] Can't Get Bluetooth Adapter To Run

I just run a system upgrade after a few days away from my Laptop.
After a reboot my adapter is now working. I suppose the reason is bluez 5.11.
Thanks all, marking as solved.

Re: [Solved] Can't Get Bluetooth Adapter To Run

I had the same problem, and it turns out you need to install bluez-hid2hci for this to work.

I guess this means bluez-hid2hci should be a dependency of bluez, because if it's not installed, bluetooth won't work out of the box for people with this sort of hardware.
