Hi Andi,
Thanks for the quick reply. I'm at work, so I won't be able to test USB until I get home in a few hours. I have an ssh connection to the machine, but that's it for now. Just in case you are wondering what address it's using for DMA, below it a copy of my lspci -v.
Thanks again for replying.
Jon
