I have the piece of gear mentioned in the title. And I have the problem on bootup that not everything plugged into the adaptor is recognized. For example my keyboard is plugged into a Belkin 7-port USB 2.0 hub that I have connected to the Kanex DualRole. But on bootup, I have to unplug and replug the Belkin hub from the Kanex before my keyboard is recognized. Other connections work fine on bootup - the ethernet connection, and the USB part of a dualLink DVI adaptor for my 30" ACD, are live immediately. Any ideas?
