The USB blaster appears to be fine. I can successfully program other boards without problems, including other boards exactly like these two.

I'm not setup on other computers yet but I could try that. Since I am able to program other boards on that programming computer, I don't feel like it is a PC problem either.

These boards did not work previously. These were assembled and failed to boot during test. After they failed, we have inspected the boards for irregularities, reflowed the BGA package FPGA, and replaced the FPGA. Nothing to this point has worked.
