Just a reminder, the Targus Universal Docking Stations do work on USB2.0 and are fine for most applications. I commonly connect to a PC USB2.0 and run two external 1080p monitors with no issue. Note, when connected to USB2.0, the docks' USB3.0 ports work to the USB2.0 specifications for power and performance. Also, the docks' GbE ports will not work at "wire speed" since USB2.o does not support more than 54Mbs. USB3.0 is best, but USB2.0 works fine for many applications and usage cases.
