I'm on my second USB hub that has flaked out. I have 4-5 devices I normally have connected to a USB hub so I have typically had a powered 7 port hub. I had a Macally one on my Windows box that worked great but when I got my Mac it stopped working. I kinda thought it was a compatibility thing even though USB is pretty universal so I bought a Kensington for $45!!!! at the Apple Store. Yesterday its like it just lost its connection or like its dead. Nothing connected to it worked including my Apple keyboard (I have the wired one). That was the first tip. But my iPhone cable is plugged into that port and it wouldn't sync this morning and the lights on my Wacom are all dead, which is also plugged into this hub. So why am I having problems keeping such a simple device working? Its got 7 ports... its not like I'm overloading it by stacking ports or something silly. The only things plugged in are formerly my keyboard and iPhone cable, a card reader, my wacom, and a USB mini cable for when I need to update my Harmony remote. I had an LG DVD burner plugged in, the kind with a Y USB cable and no power adapter so at one time, all the ports were full. Did something like the DVD burner being plugged into it "burn it out"?
