Does DMA over PCIe work using USB gadget mode with a Linux device? i.e. could a Pi be used easily and inexpensively to build an acquisition device for this?

Edit: Bleh. Nevermind. I saw this photo:

with a pcie adapter connected over what looked like USB3 and forgot that it's thunderbolt on the macbook. I was not quite to the middle of my first cup of coffee when I asked that.




Well USB is not PCIe and doesn't do DMA, so no.


Aren't most of the devices on the linked page doing PCIe over USB3?
