I am a recent purchaser of the UD-160-A docking station. I am very impressed so far.
In my office at work (where I use the dock), I have several computers connected to an IOGEAR GCS-1744 KVM switch to (obviously) allow sharing a keyboard, trackball and a pair of LCD monitors (as well as speaker & microphone, which I don’t do). When I added my (personal) Dell Inspiron 1545 laptop using the dock my various USB devices, network and the monitors worked fine (some learning about what, where & how for the monitors).
The problem is that the USB keyboard/trackball, through the KVM, aren’t detected. So I have to use the internal kbd/trackpad or a second kbd/mouse set independently connected to the dock. This is inconvenient, to say the least, and defeats the purpose of connecting the laptop to the KVM.
Since I use several computers at home w/a different KVM setup, I would consider another of the GCS-1744’s & another dock for there, if I can resolve this issue for my laptop setup here at work.
