    My brand new Z930-118, with windows 7 home 64bit, does not recognize external CD/DVD drive when I plug it in the USB port.

    The CD/DVD device does not even show at all in the device manager.

    The drive is a Samsun SE-S084 and works OK on another laptop.

    I already checked for the 'upper_filter' 'lower_filter' with the regedit but the entries weren't there, so no help.

    Hi
    Iím not quite sure how to help you.

    I found some informations about this ODD drive and it looks like it does not need an external power supply. Its USB bus powered so I assume it needs around 500mA power since this is the default value provided by one USB 2.0 port.

    I donít think that there is some missing software problem. This is an plug ní play device so you need to connect it to the USB port and the system should recognize it automatically.

    From my point of few you try to connect the external ODD to two USB ports using a *Y* USB cable.
    I think the drive needs more power as supplied by one USB port.
