I have the same scenario here. Same kernel modules loaded but audio only works if my bluetooth dongle is connected on my external self-powered USB Hub. Check out dmesg output: - Connecting bluetooth dongle over USB Hub: usb 1-1: new high speed USB device using orion-ehci and address 19 usb 1-1: configuration #1 chosen from 1 choice hub 1-1:1.0: USB hub found hub 1-1:1.0: 4 ports detected usb 1-1.3: new full speed USB device using orion-ehci and address 20 usb 1-1.3: configuration #1 chosen from 1 choice - Connecting bluetooth directly on Sheeva Plug: usb 1-1: new full speed USB device using orion-ehci and address 14 usb 1-1: configuration #1 chosen from 1 choice The only difference is the high device speed device which is my USB Hub. Can anyone help me to understand what is happening?
