I have two Acer Veriton comptuers running windows 7. In device manager it shows me a yellow triangle with a black exclamation mark inside on:
Intel (R) 82801G (ICH7 Family) USB Universal Host Controller - 27CA and 27CB.
If I uninstall these two devices and do a refresh the conflicts are gone but than later they come right back. I looked at the properties of these two devices and I see the driver date: 6/21/2006.
Like I said this just started happening on these two systems a week ago and now everytime I want to plug in anything to the USB port I have to un-install the devices with the conflicts, then I have to do a refresh and then the usb ports recognize whatever I attached to them just fine, but later they crap out again with that conflic.
