    ICH9 USB2 enhanced host controller


      I have an Acer8735G laptop with PM45 chipset, T6600 C2D, 4GB ram. I ran the latest chipset Utiity from the Intel site. When I plug in a USB hard drive or flash drive it recognizes fine. I can write from the laptop to either of thes drives. I can copy small files from the USB drives to the laptop hard drive. If I try to copy a large file (>200meg) from the USB hard to the laptop hard drive, it starts and then freezes. It freezes at different points. The drive works fine with Windows 7 32 bit. This problem is occurring with the 64 bit version of Windows 7. The only way to clear it is to reboot. Any ideas as to what is causing this ?  Thanks
