    How many devices on a USB 2.0 hub?

    I plan on using a USB 2.0 hub with five ports, but was wondering if
    the bandwidth is sufficient for all of the following:

    A FM/AM/TV tuner card
    Lilliput touchscreen
    GPS mouse
    USB keyboard
    External Audigy Soundblaster?


    I was going to put my slot load DVD-ROM drive on USB 2.0, but I think
    I'll do firewire instead.
    Does anyone else run a lot of stuff off of their USB hubs?

    480mb/s is pretty stout...

    I have a laptop in my car right now with USB 1.1 running the Lilliput touchscreen, DeLorme USB GPS, Logitech Wireless Duo, and a Soundblaster MP3+ with no side effects thusfar...

    My hub isn't even powered either... lol

    Well, I was planning on it being one with all of the devices that I run... but if I can get away with a non-powered one that would make me happy.

    Is anyone succesfully running their DVD via a USB hub (with the usual other devices: GPS, touchscreen, etc.)?

    im using dvd via USB 2.0 hub has no problems in playback. I've read the external sound blasters use a lot of bandwidth, u might be better off running 2 cables down, having the dvd on one alone and all the rest on the hub, thats wot ive done.

    You shouldn't have a problem... I'm running an Audigy 2 NX, USB 2.0 DVD/CDRW, Delorme GPS, D-Link FM Tuner, Lilliput and USB Keyboard all running and haven't had any issues...

    Sweet!

    Is that all on a powered hub, or non-powered?

    bandwidth doesnt change with powered/non powered. You will almost definately need a powered hub unless all the devices have their own power supplies.

    If you have trouble with power, just hook up a few things and then go into Administrative Tools->Computer Management, click on Device Manager, and under Universal Serial Bus controllers you'll see your hub. Double-click that and click on the Power tab. You should see "Total power available" at the top and the power being used by each device in the list below.

    the reason why it can be successful is because to the fact that all those devices connected to the hub does not take power/bandwidth all at the same time, and usb 2.0 has a generous bandwidth. lcd and ts does not take that much, audio are powered from an amps and speakers, etc.

    the difference between powered and un-powered usb hub is that with the unpowered one, you put strain on your mobo and psu by taking the +5 volts from the psu itself thru the mobo.
