Doesn't power devices plugged in without also being connected to a computer, so if you want to charge your iPod or whatever through it, you must connect the hub to the computer

It does not seem to charge the PS3's Move controllers...

Very under powered, using with an external hard drive is problematic it kept disconnecting about every hour or so. Tried it with about 4 different external drives all with power supplies and just couldn't use it. Didn't work well with any of he web cams i tried.
