I get this error message when ever I boot up the computer. I have multiple ext. hdd's connected to the computer thru powered (supposedly 2.0) usb hubs. So I go to device manager and all the hubs and hdd's are in bold letters and the ports on the computer (also adding usb port pc boards on the pci buss) are in light letters. I have been told that the bold letters indicate high speed and the lighter letters indicate slow speed. Correct? But since everything on the computer connected to PCI buss(max. speed 33Mbs or pci-express(possible 66Mbs) would by definition be "slow speed", does this error message have any real meaning? Are all computers. by this standard, "slow speed"? Not a real crucial question , but it bugs me. What's the answer?
