One of my computers has issues with USB miners (U3, nanofury stick, compac, you name it), I would generally prefer miners to use ethernet connections. Not sure if I'm in the minority or majority on this one...
To me it depends on price to add Ethernet connection. I am very happy just to use a RPI, they are cheap and easy to get at a store even if you need one quick. So usb to RPI I am fine with.
I'm worried if you go to Ethernet on pod how much cost it adds. I think a lot of miners have a RPI or two already.
