[ubuntu] usb 3.0

I have found that any usb 3.0 card (pci-e) seems to work, even those that come with a windows driver cd. these things are relatively cheap so I ordered a couple, on ebay, to see if they would work and, as far as I can tell, they do! I thought I would post this in case somebody knows anything about this as I normally eschew any hardware that comes with a driver cd as that means its windows. I find myself wanting to install another card, in another ubuntu computer but thought I would check and see if there are any thoughts on this.
