I was getting this error too for some reason. Using a Targus USB Bluetooth Adaptor and Bose QuietComfort 35 on Ubuntu 14.04.
I rebooted and did the following steps from the command line (as root):
# hcitool dev Devices: hci0 00:19:0E:18:FC:6B
# hcitool scan Scanning ... 04:52:C7:5E:85:41 Bose QuietComfort 35
# bluez-simple-agent hci0 04:52:C7:5E:85:41 Release New device (/org/bluez/1120/hci0/dev_04_52_C7_5E_85_41)
# bluez-test-audio connect 04:52:C7:5E:85:41
And now it's all working perfectly. Not entirely sure what I did before this but I think I removed the device completely.
