Hi all, Just wondering what is the status of "bluetooth disabled with current 2.6.38-rc4" from Justin (http://www.spinics.net/lists/linux-bluetooth/msg10745.html) and "[BUG] usb problems in .38-rc3+"" (http://marc.info/?t=129693396800003&r=1&w=2) from Ed? (apologies for not being able to reply to those threads) The first one because I think I see the same problem and the second one because for me also "hciconfig -a" makes the bluetooth adapter work. Maybe they have a common cause. For me, reverting 23bb57633df ("Bluetooth: Fix __hci_request synchronization for hci_open_dev"; suggested by Justin) on top of 2.6.38-rc6-166-g493f335 makes everything work as before. bluez version and bluetooth adapter model: [root@koni ~]# pacman -Qo /usr/sbin/bluetoothd /usr/sbin/bluetoothd is owned by bluez 4.89-1 [root@koni ~]# lsusb | grep i.Tech Bus 003 Device 002: ID 13dd:0001 i.Tech Dynamic Limited Part of bluetoothd -d dump below. The printout only really got started when I run "hciconfig -a" after 22:01:42 (hciconfig hci0 down and hciconfig hci0 up can also be used to make it work): [root@koni ~]# hciconfig hci0: Type: BR/EDR
