I would recommend the SubWay if you have a clockport available. I bought one 2-3 months ago from SoftwareHut and plugged it into a spare clockport on my X-Surf and it works great. It also comes with Poseidon. I now use a LogiTech optical mouse and a MicroSoft multi-media keyboard with my A2500. I have also tried various USB thumb drives without problems. It comes with 2 backplanes for your A2000 that give you 4 USB ports.
