  • Powered USB Hub?

    Can anyone recommend a powered USB hub that lets me set it to ONLY give the devices power from the power supply, not the USB bus? For the life of me, I can't find one anywhere!

    I'm running a PowerPC Mac mini in my Jetta, with the CarNetix P1900. I want to use the optional P5V output to supply switched power to a USB hub.

    I bought one from Amazon by belkin, that has a switch for either self power or bus power (I want to ONLY use self power so the USB devices don't draw any current while the computer is sleeping). However, the hub I got needs 7.5 volts of current. I figured this out when I wired it all up, and the P1900's 5 volts weren't enough to keep the hub powered.

    Thanks!

      I think Thanatos has just made a USB thing that powers USB devices seperate from the PC. I saw the thread for the first time today, so it is recently new.

        Thanks for the help guys. Dejan, Canyon's site says it requires Windows (which I'm not totally sure is a 'requirement.'). I'm running Mac OS X, but it should work. I'm just a little leery since the description on the site doesn't assure me there's a way to only use self power.

        I couldn't find Thanatos' post, but I'll look again harde when i get more time. Thanks.
