    Exclamation WTB: USB 2.0 Hub powered from 12v

    How the hell do ya'll have a powered USB hub in your car without an inverter? hook up some resistors to the 12v line or something first???

    Anyways, anyone willing to make/sell a usb 2.0 hub that can be fed the 12V line ill be willing to buy, if not too pricey...

    Just a tip, don't bump your thread after 8 minutes. You will get a lot of people who won't respond if they see that.

    Most powered hubs take 5V. For $25 you can get the Carnetix 5V POL which will be enough for a 4 port hub. Opus makes one as well, and both are listed below.

    Most hubs say 6v, but will take 5, run a wire from your psu.

    The reason I didn't suggest running it from the PSU is he doesn't seem very knowledgable with electronics. With the 5V POL, all he needs to know is how to connect a few wires rather than splicing wires or creating an extension with connectors.

    What do you need to power? I have an 8' USB extension to an unpowered hub which I have a WirelessG adaptor, keyboard and touchscreen attached with no problems. Are you sure you NEED power?

    You could also just run more extensions maybe...

    Actually electronics is no problem for me, the reason i dont run it from a PSU is cuz im using a laptop mobo that runs from the standard laptop PSU...

    I am trying to run: wifi card, GPS, touchscreen, and an external usb 2.0 DVD drive... (possibly TV/FM tuner later) it works half the time without the 5v power attached, and, when playing a DVD in FP, it seems to be using up all the ram, and the virtual memory, then crashes stating that theres not enough virtual memory or some junk.... the original ATAPI DVD-rom (attached to mobo) works fine... its something with the usb bus that makes it all wierd...

    how much current does a laptop CDROM draw????

    any suggestions are welcome

    he said he's running a laptop...therefore won't have a place to plug in your molex connector.

    edit: i had a external HDD that drew power from the PS/2 port, maybe you could hack that.
    I'mmmmmm a n00b.... feel free to make fun
