Question about USB 2.0 as it appears in the Device Manager

Hello,

I have 16 entries under the USB Controllers section of my Device Manager. This is the breakdown:

1 x Generic USB Hub
1 x NEC PCI to USB Enhance Host Controller (B1)
2 x NEC PCI to USB Open Host Controller
1 x USB Printing Support
7 x USB Root Hub
4 x VIA Rev 5 or later USB Universal Host Controller

I bought a USB 2.0 card into which I plugged a 4 port USB hub. I now have an Epson 4990 Photo scanner that I will be doing relatively high-res scans with, and I don't know if it's actually plugged into the right USB port.

I know that USB 2.0 is generally described as 'enhanced' in the DM. Is there any way to tell though if my scanner is plugged into it?

Thanks-

Thanks guys, sorry for the late reply... I think I've got it figured out. At least (as garycase mentioned) "USB 2.0" shows in the balloon when I plug in the scanner. But a silly question for you nobus: how can I tell which port corresponds with that entry?

Garycase: the hub is definitely 2.0 and powered, so I'm covered in that area.

>> how can I tell which port corresponds with that entry << All the usb connectors on the PCI card are usb 2.0 - that is what it means
