I am having a few issues with my new Dynadock u3.0.
First of all, all of the USB connections are working as well as the usb ethernet. The only two issues I am having are with the usb audio and the usb displays. I am running Ubuntu 12.10 on System 76's newest Lemur Ultra. I will try to provide as much information as possible.
Right now I have connected to my dock: a Razer mouse, Logitech keyboard, Oyen external hard drive. My displays are a Panasonic, Samsung and HannsG(plugged in directly to laptop via HDMI) and my speakers are an Insignia.

So for the sound I see that the sound card in the dynadock is recognized by my OS, but the GUI for managing sound doesn't seem to pick it up.
As for the displays I have no idea where to begin, I've been researching, but nothing seems to work. I understand that you need a displaylink driver and that some exist for Linux. I even read that the driver has been added to the Linux kernel itself, but I haven't verified that. Anyways, if there is anymore information that I need to give I will be glad to post here.
