Well, you are trying to use the board in a non-standard environment; you shouldn't really expect it to work out of the box. How did you flash the board with the "base.aocx" file via JTAG? This file needs to be first converted to SOF and then used to flash, it cannot be directly flashed via JTAG. If your board is flashed correctly, it should show up in device manager as a PCI-E device with some name that has "Altera" in it.

If you have a machine with a PCI-E slot, I recommend first trying on that and making sure the board works correctly, then putting it back into your Thunderbolt enclosure and following the same steps.
