Folks,
Where can I learn how to optimise and measure USB performance. Motherboard has build in ports and have a hi speed dual card in a PCI slot. Also front of PC has two ports. How can I check what they can do? And learn about installing drivers etc.

USB 1.1 transmits data at 12 mbs(megabits per second), and USB 2.0 at 480 mbs.
Device Manager lists 1.1 as USB, and 2.0 as 'Enhanced USB'.
Connect devices that transfer a lot of data, like printers, cameras, video cams, etc., to the USB 2.0 ports.
