Hi all,

I wonder if anyone could help me to get my USB BlueTooth dongle working
please?

I have the Debian package of bluez 4.99 (Debian version 4.99-2). I also
have the Debian bluez-firmware 1.2-3 package installed.

When I plug it in I see

[587526.800544] usb 2-1.6: new full-speed USB device number 9 using ehci_hcd

in dmesg. If I then run "hcitool dev" then I get

$ sudo hcitool dev
Devices:
$ 

I'm told that this is because it is in HID rather than HCI mode, so I
try:

$ time sudo /lib/udev/hid2hci --devpath=devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6:1.4/input/input11 --method=csr
sudo /lib/udev/hid2hci  --method=csr  0.00s user 0.00s system 0% cpu 10.070 total
$ echo $?
0
$ 

which takes 10 seconds and adds this line to dmesg:

[587720.123420] usb 2-1.6: usbfs: USBDEVFS_CONTROL failed cmd hid2hci rqt 64 rq 0 len 0 ret -110

The other 2 methods instantly fail:

$ sudo /lib/udev/hid2hci --devpath=devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6:1.4/input/input11 --method=dell
error: switching device '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6:1.4/input/input11' failed.
$ echo $?         
0
$ 

$ sudo /lib/udev/hid2hci --devpath=devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6:1.4/input/input11 --method=logitech-hid
error: could not find hiddev device node
$ echo $?         
22
$ 

None of them alter the output of "hcitool dev".

Am I doing something wrong? Or is my dongle just not supported?


Thanks
Ian
