I noticed recently that for some reason,my USB ports aren't being identified as 2.0 ports, but I know they are. My computer is an ASUS CG5270, Specs: Core 2 Quad @ 2.4 GHZ,8 gigs ram, 750GB hard drive. I tried going into the device manager and uninstalling everything under "USB", and then restarting and replugging everything in..no luck. I found some Fix for Windows 7 SP1...no help. Whenever I go into the Device Manager, there are two ports ( I think they're ports) listed as "Enhanced", with the rest as "Universal". I keep getting errors when I plug in my external HD that "this device could perform faster". (I also get another message telling me that the drive needs to be formatted, but it works anyway) Any Ideas? I'm going crazy! I also get a "this device could perform faster" with my webcam, as well...

I do not know of anything that could do more about diagnosing your problem that you haven't done. There is software that would measure your transfer rates, but it seems you already know that. Since everything necessary is set up correctly, there is still something that is not recognizing the USB 2.0 devices. A new motherboard may be needed.

Before you do that, perhaps blow out the unit in case some dust might be causing a problem. Before you decide to replace the motherboard, you might want to try unplugging the unit and use whatever procedure ASUS recommends to reset the bios. Some boards have jumpers, some systems seem to be able to hold the power button for several seconds or whatever else. Resetting the bios to it's...

reformatted (instead of just installing a new copy of windows over the old one) ...I installed the chipset drivers and everything. System BIOS has USB 2.0 enabled, and set to high speed. Legacy support is on. Lets say for the sake of argument that this is an issue on the hardware side, possibly related to the MoBo. How would I go about diagnosing/fixing the problem?

Some boards have jumpers, some systems seem to be able to hold the power button for several seconds or whatever else. Resetting the bios to it's defaults might even help, but make note of your settings before you do that or the other procedures. There is always a chance some glitch in the bios is causing the problem.

Maybe someone else will have another suggestion ....

I reset the bios, nothing really changed unfortunately.

I noticed there're some jumpers around the MoBo, is it possible that they're not properly configured? If that were the case, could it cause the slow-downs?

I cleaned out as much of the dust as I could, to no good result. I think I'll just take my computer to Geek Squad and see what they can do. I'm covered by them by my computer's warrenty, or else I'd never go near the place
