A 6 month old system should be entirely USB2.

You will see either one or two "Enhanced" entries in the Device Manager.
Two Enhanced entries is enough to control up to 12 USB2 connectors. The
entry corresponds to the logic block controlling the connectors, rather
than being "one per connector".

Check the BIOS first. I got surprised once, when USB2 seemed to be
turned off on my system. And I did not remember changing the BIOS
setting, and yet USB2 had been disabled at the BIOS level. Check
that first, in the BIOS setup screen. The key to press, to enter
the BIOS, should be printed on the screen at powerup.

Sometimes, detection of USB2 fails. And one solution, is to delete
the entries in Device Manager, and let Windows detect the hardware
again. Example here. This might happen, after a Service Pack upgrade.
