    I've been having a problem with a usb hub (no name hub) and my Intel iMac.
    Normally, all that I have plugged in to it is this:
    1. 1GB Shuffle
    2. 2GB Shuffle
    3. 8GB 2G iPhone
    When I wake up my Mac, one or more of the devices will no longer be listed in iTunes.
    I thought that maybe it was my generic usb hub so I bought a Tripp-Lite. It's doing the same thing.
    I've been using the port that is closest to the outside of the Mac. Now, I'm going to move it in to the inside port.
    By the way, I'm using a brand new usb cable from the Mac to the Tripp-Lite hub.

    The other ports are used for a camera and for a printer. My keyboard and mouse are wireless.

    Any ideas?

    Powered or unpowered hub? You may be experiencing the infamous Mac issue of insufficient power to the USB ports. If your Tripp-Lite isn't powered, I suggest you try a powered hub, they're cheap enough. If you want portability as well, I can recommend the Cyberpower unit, which is powered by 4xAAA Ni-MH batteries, which have optional recharge from your USB port.
