    One PC with Windows XP Home edition could not boot yesterday. When booted in safe mode it hanged at gagp30kx.sys. Run system restore, it did not work. And I renamed gagp30kx.sys via Recovery Console, it still did not boot and hanged at mup.sys which was listed above gagp30kx.sys before I renamed gagp30kx.sys.

    It finally booted after I disconnected the Wireless USB adapter. But when I reconnect the adapter the PC hanged again.

    I tested different UBS devices with the same port, some hanged the PC and some not. Before yesterday, all of the devices were working fine on that PC.

    Here are my test results:

    Canon i550 printer : working
    64 mb flash drive: working
    2 G flash drive: not working
    ZyXel Wireless 11b/g USB Adapter: not working
    Portable hard drive: not working

    Could anybody help me to identify the reason of the problem?

    Many thanks in ahead.

    It sounds as if the boot order in bios has ubs boot before hard drive.
    Go into bios and check that boot priority is hard drive first, remember to save the setting before exiting.

    Thank you for answering my question.

    The problem now is that after I boot that PC successifully, if I connect the some UBS devices, such as a 2G flash drive, it will hang the PC (mouse, keyboard no response). What puzzles me is that the small flash drive won't hang the PC. Does it indicate a corrupted drivers or some kind of virus?

    Thanks.

    You could try reinstalling the usb drivers.
    Try this fix by JohnWill



    Create a file with NOTEPAD containing the following lines and save it as FIX.REG
    -------------------------- Use text after this line --------------------------------
    REGEDIT4

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

    "DEVMGR_SHOW_NONPRESENT_DEVICES"="1"
    -------------------------- Use text before this line --------------------------------

    Double click on FIX.REG and say yes to the Merge Into Registry question.

    Unplug ALL USB devices.
    Open Device Manager.
    View, Show Hidden Devices.
    Uninstall all devices under USB Controllers.
    Uninstall all devices under Disk Drives that you know are not present.
    Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
    If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

    When this is done, reboot TWICE.

    Reconnect the USB devices and see if they're recognized properly.

    NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

    Bigbear,

    I tried it, but no luck. It still has the same issue.

    After uninstalling all of devices as you suggested, and reboot the PC twice, the PC recognized the small flash drive right away. When I plugged in the big flash drive, PC did not have any response, but it did not freeze at that moment. However, after I took out the flash drive and replace it with smaller one, the PC hanged again.
