Read data through USB blaster

I have this custom board that has no JTAG connector (set up for Active Serial with an EPCS4 flash). I can load a NIOS2 on it using tricks learned in this forum and I can flash LEDs on board. Is there...

ok, I should have been more clear. I do have a 10pin connector on the board, but the JTAG lines to the FPGA (TCK, TMS, etc) are grounded. I program in active serial mode. But then I have no way of sending data back and forth. Hence my thought to repurpose the blaster as a generic SPI IO. Seems like is doable based on what you said, so I guess there is some reading in my future.

Thanks!
