Devices:

$ hcitool scan
Device is not available: No such device

$ lsusb | grep Bluetooth
Bus 002 Device 003: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)

$lsmod | grep bluetooth
bluetooth             150884  10 rfcomm,bnep

Re: [SOLVED]Bluetooth didn't work!

If I'm not mistaken, this BT device should be supported by "hci_usb" driver. Do you have the driver enabled in the kernel? Can you modprobe it manually?

EDIT: The driver's name is actually "btusb", I'm sorry for any confusion.

MadCat_X ,thanks.I think you may right.I had modprobe btusb,and rebooted my computer.It didn't work.Here is my driver in /lib/modules/3.1.2-1-ARCH/kernel/drivers/bluetooth/

$ls /lib/modules/3.1.2-1-ARCH/kernel/drivers/bluetooth
ath3k.ko.gz        bpa10x.ko.gz       btsdio.ko.gz     dtl1_cs.ko.gz
bcm203x.ko.gz      bt3c_cs.ko.gz      btuart_cs.ko.gz  hci_uart.ko.gz
bfusb.ko.gz        btmrvl.ko.gz       btusb.ko.gz      hci_vhci.ko.gz
bluecard_cs.ko.gz  btmrvl_sdio.ko.gz  btwilink.ko.gz

Should I modprob other to enable in the kernel?Or shoud I do some other jobs?

Re: [SOLVED]Bluetooth didn't work!

after manually modprobing a driver DO NOT reboot.

test if you have the desired functionality, and if so add btusb to the modules array in rc.conf so it will be loaded at next boot also.

Re: [SOLVED]Bluetooth didn't work!

Also note that BCM2046 has to be switched from HID to HCI mode by hid2hci tool. UDev should handle this automatically, but in case it doesn't it's another thing you should look into.

Re: [SOLVED]Bluetooth didn't work!

Hi，guys.I had read the wiki of bluetooth ,and I noticed that "On some Dell laptops (e.g. Studio 15) you have to switch the Bluetooth mode from HID to HCI using."And my laptop is dell.So I try to use hid2hci to switch my bluetooth from HID to HCI .I noticed hid2hci is no longer in the $PATH, it is under /lib/udev/hid2hci ,I located the path of hid2hci.The path is Correct: /lib/udev/hid2hci.I run the command.

# /lib/udev/hid2hci
error: --devpath= and --method= must be defined

Usage: hid2hci [options]
  --mode=               mode to switch to [hid|hci] (default hci)
  --devpath=            sys device path
  --method=             method to use to switch [csr|logitech-hid|dell]         (I have a logitech keyboard)
  --help

It' said that the parameters of hid2hci must be defined.I searched online.Someone says run the command lshal,could find the devpath.The lshal include in hal,but the hal is deprecated and has been dropped from the official repositories.It' in AUR now.I'm a newcomer from Debian,and I don't know how to use AUR.Can you tell me other way to got the DEVPATH?And other thing should I  pay attention when I run hid2hci.

After I manually modprobe the btusb ,I had checked using hcitool.However got this:

$ hcitool dev
Devices:
$ hcitool scan
Device is not available: No such device

Just as MadCat_X said,I should switch the Bluetooth mode from HID to HCI using hid2hci.But I couldn't find DEVPATH of bluetooth,when using hid2hci.Any advise?Buy the way,hal is deprecated and has been dropped from the official repositories,so I can't use lshal.

Re: [SOLVED]Bluetooth didn't work!

There might be a less obnoxious way, but I believe that devpath to my BT device can be obtained like this

lspci

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 04f2:b008 Chicony Electronics Co., Ltd USB 2.0 Camera
Bus 008 Device 002: ID 08ff:1600 AuthenTec, Inc. AES1600
Bus 008 Device 003: ID 0930:0200 Toshiba Corp.  <-- My BT device

Using VID and PID from lsusb

udevadm trigger --dry-run --subsystem-match=usb --attr-match=idVendor=0930 --attr-match=idProduct=0200 --verbose

/sys/devices/pci0000:00/0000:00:1d.2/usb8/8-2

There I go.

My BT device works out of the box so I can't check if it's exactly the path hid2hci expects.

Re: [SOLVED]Bluetooth didn't work!

Thank you MadCat_X .
I noticed that my Dell Wireless 365 Bluetooth device matched on a mouse device.And I found the Vid and Pid of my BT.

I read the rules file of hid2hci in /lib/udev/rules.d/97-bluetooth-hid2hci.rules.My BT is in the supported devices list: 413c:8154, 413c:8158, 413c:8162.
The devpath is : /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0/
So I run the follow command:

# /lib/udev/hid2hci --mode=hci --method=dell --devpath=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6.2/2-1.6.2:1.0

But nothing happened.

]# hcitool dev
Devices:
# hcitool scan
Device is not available: No such device

Is there some bugs in the bluez 4.96-1?Or,the --devpath of hid2hci is wrong? Please help me!

Re: [SOLVED]Bluetooth didn't work!

I'm sorry I nearly forget the post! The bluetooth worked two mouths ago.So I put it here for someone who had the same problem.
My bluetooth is Dell Wireless 365 Bluetooth.
I get the idea from this post:https://bbs.archlinux.org/viewtopic.php?id=124166
I install the vritualbox ,and setup a XP,then pulg the bluetooth into xp as usb(it treat as a usbport).Then ,you shoud get the driver for Dell Wireless 365 Bluetooth in the XP install.Turn the bluetooth on !After all my bluetooth back.And it work well now.
By the way ,I'm very sorry about my poor English.

Re: [SOLVED]Bluetooth didn't work!

SOLVED by installing Windows XP in VirtualBox - are you serious???

I tried to run hid2hci. But like Asarorschach I was not able to find a valid devpath. I also tried comment #9 of MadCat_X without success.

This problem looks similar to a bug that appeared in late 2011 with Broadcom bluetooth hardware too:
  http://launchpad.net/bugs/839157
  https://bugzilla.redhat.com/show_bug.cgi?id=747575

If you find further details about this problem, please help by reporting them to one of these bug trackers.

Re: [SOLVED]Bluetooth didn't work!

hi, I hope it's not too late for a response.
long have this problem, I have Gnome 3 and bluetooth does not work, the problem is in the btusb module, which is given by the kernel, so remove the modulewith

sudo rmmod btusb

and then reload it again

sudo modprobe btusb

and thus the bluetooth works, it is not the final solution, and should be done every time the machine is turned on but where is the problem.
