Bug Description

Binary package hint: bluez-utils

I have a bluetooth usb dongle which has worked under Linux before. It works with Windows too.

When I insert it, kernel apparently recognises it as dmesg lists the device. Even lsusb displays it. But when I run hcitool scan it reports "Device is not available: No such device" This is under Edgy.

From dmesg:
[ 1277.247754] usb 1-1: new full speed USB device using uhci_hcd and address 2
[ 1277.367746] usb 1-1: device descriptor read/64, error -71
[ 1277.768802] usb 1-1: configuration #1 chosen from 1 choice
[ 1279.216506] Bluetooth: HCI USB driver ver 2.9
[ 1279.222615] usbcore: registered new driver hci_usb

From lsusb:
Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

sudo hciconfig hci0 up

seems to help but this wasn't documented anywhere. Currently it finds my phone but hcitool auth xxxxxxx times out.

You seem to have USB 2.0 while I have USB 1.1.

It works for me (Ubuntu 6.06.1 Dapper).

I suspect it's a problem in uhci_hcd (Kernel bug then)?

You are using wrong command.

To scan for local devices (bluetooth dongles) the command is 'hcitool dev'
'hcitool scan' scans for remote devices. Please check 'man hcitool'.
