USB 2 Maximum Cable Length

    My backup device is a USB 2.0 250 MB Iomega Hard Drive.I'd like to put
    it in my garage, requiring about 20 to 25 feet of wire. The official
    USB specs say 5 meters max; if further use a hub/repeater.

    I'm wondering how realistic the 5 meter spec is. I recall tha
    printer cables were supposed to be limited to 10 feet or so; 75 foot
    cables worked just fine. Same thing with the specs for RS-232 cables.

    Does anyone have any real world experience with long USB 2.0 cables?
    I'm thinking of building mine using unshielded CAT5 cable, one twisted
    pair for power, another for data. Wise? foolish
