I came from radio shack and they only have converters that drop to 4.5 or 6 volts. None were 5V. So i bought a 24 guage spindal and am going to give that a try...

    I will post my results. Thanks for input...
    Sounds like you have it pretty well isolated to wire length. You could be seeing more than half a volt drop with 18 gauge wire @ 15 feet. I estimate going to 12 gauge will bring it about equivalent to 18 gauge @ 5 feet. 10 gauge should make it a moot point. Remember, lower gauge = larger wire. You don't want to be using that 24 gauge wire...

    you sure its the power wire that is causeing it? does the computer communicate withe the cdrom ok? if not then it could be somehing to do with the usb lead.

    else you could be picking up some interferance on the 5v power line, try useing wire that is twisted or has a braided shild.

    I've got probably 12+ft of (cheap) speaker cable running from the Opus in the boot to the front of the car, and that is powering a USB2 hub, USB2 to IDE adapter and slimline DVD-rom drive without a problem.

    Most of my problems have been due to the USB-IDE adapter not being detected!

    Ditto. I HIGHLY doubt it's the power wire. But there's only one way to find out.

    Ok well Im now officially stumped... I tried the higher (24 guage speaker wire) and was unsuccessful. I'm now limited to only 1 foot where as before I was capable of 5 feet with 18 guage(wierd huh?). Im positive that this is a power issue. Ive done enough troubleshooting to pretty much rule everything else out.

    I tested the 24 guage at 1 foot with the cd-rom playing music looped for 20 minutes, I did this same thing for the 18 guage at 5 foot. To ensure that it wasnt interminitten...
    Anything after the allowed length will result in the cd-rom LED blinking rapidly and sounding like its spinning up then stops in a loop. During this time I can see the drive on my PC but it is unable to read the CD in the drive. The usb cable is directly pluged into the PC to avoid possible faults with the usb HUB.

    Ive also tried this with another laptop drive that i ripped from my IBM and same results... Thanks for the input so far ppls... Let me know if anything further comes to mind...

    24 gauge wire limiting you to 1 foot does reinforce the theory that it's power. Now use a larger wire instead of a smaller one! Read my previous post, and remember, gauge number is inversely proportional to wire size.

    I did read your previous post and was meaning to comment on it. I thought that the higher the guage the less current used, the more power the device has...(when dealing with a small amount of power such as 5 volts). However the more voltage requires a lower guage to avoid heading up the wire.

    Thanks for your help I plan to give it a shot tomorrow...

    What length USB cable and is it definitely a USB 2.0 cable? Has the length of USB cable ever changed?

    I'm talking the cable, not the ports.
