Yeah not glamorous but needed usb2 ports.. I purchased an allegro usb pcie usb adapter card it cam today. just hooked it up. it is driverless it works from the getgo. 4 jacks on the outside 1 on the inside. has a four prong power adapter inside. purchase link. owc 60 bucks. http://eshop.macsales.com/item/Sonnet Technology/USB2E/ number one it has solved my problem with my external sound card I have a 4 year old edirol external sound ua-1ex. this is a nice little device and it was not working correctly with the 2010 mac pro i had to plug it in and out after every boot. now it just works. i also needed more usb2 ports and they all seem to work. I will give a few speed tests for them tomorrow. so far i like the card. after a few hours of playing with it.
