Have you tried to determine whether its a power-on reset timing issue?

For example, if your FPGA does not configure before the BIOS enumerates, then the board might not enumerate correctly. You can diagnose this problem by powering-up your PC, and then hitting ESC (or whatever) to enter the BIOS, and then exit the BIOS and allow your machine to "warm boot". Ideally you could monitor an LED on the Stratix V board to confirm that its configured before you reboot, and that it stays configured during this warm boot sequence. If the board is correctly detected after the warm boot, then you know what the problem is, and a work-around.

Cheers,
