|If the mboard was made after about 2003, it supports USB 2.0. |
You don't need to be looking for USB 2.0 drivers. The support is already there in the operating system, but the main chipset drivers have to be installed before it's installed.
All Microsoft operating systems Win 98 and up install USB 1.x support automatically when you install the operating system. USB 2.0 controllers also support USB 1.1 .
Installing the main chipset drivers for the particular mboard after Windows Setup has finished installs the USB 2.0 support, if the mboard is capable of supporting USB 2.0. The USB 2.0 support is built into the Windows 7 (and Vista, and XP with SP1 or greater updates) operating system, but the main chipset drivers for the mboard have info (in *.inf files) the operating system needs to know in order to enable the proper USB 2.0 support, so the USB 2.0 support is not installed until the main chipset drivers have been installed.
Since you say you installed the drivers for the mboard, assuming you installed the main chipset drivers, the USB 2.0 support has probably already been installed.
Take a look in Control Panel - Classic View - Device Manager - Universal Serial Bus Controllers.
If you have a listing for an Enhanced USB controller of some sort, the USB 2.0 support has already been been installed.
- If you only get the message when you plug into the front USB ports, for some computer cases, the case wiring between the ports and the USB header on the mboard is inadequate and it cannot support USB 2.0 specs. That's more likely to be the situation for an el-cheapo computer case.
If you're handy, if you replace the inadequate wiring with wiring that supports USB 2.0 standards, the front ports will then work fine for devices that work better if the port supports USB 2.0 .
- I have seen a few cases where you get the message when you plug into SOME directly connected to the mboard USB ports on the back of the case in the I/O area where most of the ports are, but not from others there. Try another port there in that case.
- You MAY get the message in other circumstances regarding USB ports not physically built into the mboard.

Also - if you are using a USB extension cable, some of them have inadequate wiring and will not work properly with some USB devices.
