www.nirsoft.net has a similar but complementary utility, USDDeview. Between USBDeview, USBView, and the Dev Mgr, I can mostly figure out which USB ports are what, and what they ports are doing. Two cautions: (1) none of them will tell you precisely which port is "really" USB v 2.0 or 1.0. (2) the Hub numbers jump around depending on the order in which you plug in a device to a port; but the port numbers do stay fixed. (Thus, Hub 1 Port 2 may become Hub 3 Port 2 when you plug something into Hub 0.)
