I have a m1160n media center. It has never recognized the 6x USB 2.0 ports. It always says "You're device can run faster if you connect it to a 2.0 port." It then lists 8 that are available. This computer only has 6 and they all give the same message above. I get this message when I connect my iphone 3GS. I have a laptop with 2.0 and it works fine. Also has Windows XP. I have already tried the reinstalling of the drivers. searching for new ones, and a restart. It didn't work. Help?

One of the devices on the USB hub with your iPhone is probably a USB 1.0 or USB 1.1 device. This will cause the entire hub to run USB slower. Try moving the iPhone to a different USB port.
If you have two USB 1.x devices then plug them into the same hub (in the back for example) and use the front hub for USB 2.0 devices.

Don't worry about 8 usb ports. You have 4 on the back and 2 in the front. The other two are probably assocaited with your memory card reader.
Go into Device Manager and find the universal serial bus controllers. Right mouse click on each hub and go to the advanced tab. You should see some indication of speed operation such as:
High Speed which equals 480 Mbps
Full Speed which equals 12 Mbps
Low Speed which equals 1.5 Mbps
What does each root hub indicate for speed? If you see a RESET HUB button then reset each of the hubs.
If your root hubs don't indicate High Speed or possibly Full Speed then that is probably why you are seeing the message.
If you are running XP then be sure that you are running service pack 3.

Unfortunately stilla no go. The Hubs don't have an advanced tab, only the "SiS 7001 PCI to USB open host controller" listings under USB Controllers have that tab and they just list the percentage of bandwidth each USB controller is using. It shows 10% and says it's fixed. There isn't a reset HUB button, only refresh and that does nothing. I am also running service pack 3. Any other ideas?

I'm thinking you are missing the SIS USB 2.0 driver.
Take a look at this and see if this will help you:
