USB controllers conflict in device manager

hi experts,

 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.

help!

right click it, properties, details, click on hardware details.
usually the first item is the hardware ID of the conflicting item. post it here and I'll bring the missing driver.

An alternative solution is to use Drive Pack Solution (http://drp.su/download.htm) and run the tool, when it find the drivers missing or needs updated, click update.

what pc 's are this?  model plse
best download the drivers from the manufacturer site -  and  update all drivers

in case it can be malware; i suggest to run an updated AV scan + these :
http://www.malwarebytes.org/mbam.php                         MBAM
http://majorgeeks.com/RogueKiller_d6983.html                  Roguekiller

and you can always test if the usb works fine when booted from a live Knoppix cd
