[Bluez-devel] usb-2.0 hub problem

[Ruben Jenster]

Trying to transmit some audio data to my headset fails, when the bluetooth 
dongle is attached to a usb-2.0 hub. I allready commited a bug to the kernel 
bugtracker but there no one is able to help me.

http://bugme.osdl.org/show_bug.cgi?id=4358

The dongle works perfectly when attached directly to the motherbord.
When attaching it to the usb-2.0 hub I get the following message:

usb 3-3.1: new full speed USB device using ehci_hcd and address 5

Maybe someone here is able to help me.

Ruben
