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.

Recognized Sound Devices

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.

the Chip is likely a : DL-3900 – TiloBunt Jan 24 '14 at 0:31

There is a display link driver for linux built into the kernel; however, due to the complexity of the dl3000 series chips in the new displaylink usb 3.0 docking stations, there is still no driver available for linux.

Display Link has released a new Ubuntu driver (for 14.04 LTS).

This driver will support up to 2 displays connected to DisplayLink devices. More than 2 DisplayLink displays may work, but not supported or tested by DisplayLink. Resolutions up to 4K are supported on the appropriate DisplayLink hardware.

Device families supported are:

  • DL-5xxx
  • DL-41xx
  • DL-3xxx
