I have an Acer Aspire 8735G running Windows 7 home premium 64 bit. I have a clean install and all the latest BIOS and drivers from the manufacturer. It also in NOT running Nvidia chip for the USB enhanced controller. It is an Intel controller. When I use any USB hard drive, the transfer starts then stops responding part way through. It seems to stop at various points in the transfer. I have to reboot to get the USB port to start working again. This happens with large files and folders with a large amount of files within. Can anyone help ?

Thanks

    This installer and file package might be of interest. It would appear to cover Windows 7 64 bit. The written file description gives no indication of it but the contents appear to be written to include appropriate installation and support files for your chipset. But what do I know? I'm bankrupt of ideas, flat and forlorn. :-))

    So that's it.  No more ideas from anyone.  I hope Microsoft or Intel comes out with some kind of update. Not being able to copy large files from a USB drive is a real pain in the butt. Searching the internet shows this to be a fairly common problem, USB and Windows 7,

    Unfortunately that won't help me. I 'm using a laptop and the BIOS doesn't have very many options.

    Hello again, i came across a posting about file transfer problems in asus mainboard forums which suggested disabling the "USB to EHCI hand-off" in the bios. Thats enabled by default for the mobo i have, m4a79. I dont yet know if it completely solved the problem but its certainly an improvement as i was able to transfer 8 gigs from a thumb drive without freezing right after a cold boot. I'll try an external hdd with larger files and post the results..

    I tried your idea of having the hard drive plugged in during boot up.  I was able to transfer the file with no problem. When I tried to transfer the file again on the same bootup  it locked up and I had to reboot.  If I go into device manager and disable the enhanced USB controller(in my case ICH9 usb2 enhance host controller) I can transfer files all day but they transfer at 1.1 speeds, SLOW. I hope one of the Microsoft wizards finds an answer soon. It definitely seems to be a 64 bit problem.
