What is wrong? Thats interesting. This product: http://www.griffintechnology.com/products/usbaudio_hub/ claims to be a "USB Audio" hub, and I always thought it was BS, but maybe theres some truth in it. Sorry I dont have any helpful suggestions :( It could be that the audio device is trying to draw more power from a single port than the hub or docking station wants to provide, you can find out by running lsusb -vv as root and looking for the MaxPower line of your audio device and the power allowance (dunno what thats called) of the hub. The docking station will probably be a hub too. - Steve
