usb port drivers

[morris44]

On my Dell ATG laptop,  I notice in Device Manager that there are  4 USB Universal Host Controllers (drivers) and one Enhanced USB2 driver. I only have 4 physical usb ports on this laptop. They are all addressed differently but I would like to know what physical USB port has the Enhanced USB2 driver. Maybe it is automatically invoked when connected to any of the 4 USB ports on the ATG with a hi speed USB 2.0 device?  Can I have more than one hi speed USB 2.0 devices connected at the same time? Thanks.

I don't know your answer, but an easy way to determine this would be plug a USB2 device (a larger "thumb drive" memory stick for instance) into each of them. If any aren't USB2 you will get a little pop up ballon message saying that your experience can be inhanced by using a USB2 port and to click on the balloon to see which ones are. I suspect they all are. Remember to use the little icon in the lower right tray to "safely remove hardware" whatever USB2 device you plug in before you unplug it. I have never trashed one, but have heard from different people that just unplugging without the release is bad.  One note: if you use usb to serial comm port adapters their serial comm address (COM6 for instance) will be different depending on which usb jack you plug into.

FYI

Got this from tech support from Dell about USB ports

" I was informed that all can be used as USB 2, the others use pass-through technology to make all of the others use the USB 2 speed."
