How do I blacklist or otherwise permanently disable the sound card on the docking station, while keeping the ability to use usb sound devices and the ability to use the other features of the docking station?

Hardware:

• I have a usb soundcard based set of earphones. Bus 002 Device 014: ID 046d:0a44 Logitech, Inc. Headset H390
  


• I also have a Dell D3100 docking station that I use as a USB multiplier and to run an additional screen. These usb devices I believe are related to the USB Hub:

Bus 003 Device 005: ID 17e9:436e DisplayLink 

Bus 003 Device 004: ID 2109:0813 VIA Labs, Inc.

Bus 002 Device 005: ID 2109:2813 VIA Labs, Inc. 

Bus 002 Device 003: ID 2109:2813 VIA Labs, Inc.
