I am currently using a Belkin 4 port USB hub (model f5u021) and when I connect any of my Ipods (Nano video, and Mini) is tells me I do not have enough power to run device. When I plug it straight into the iMac no problems. Question... Is this normal or do I have a crappy hub? I am betting it is a crappy hub here is a link http://catalog.belkin.com/IWCatProductPage.process?Merchant_Id=&Product_Id=93743 I do have the AC adapter plugged in. Any input would be greatly appreciated.
