Hi,

i have exactly the same problem using Quartus 10.1 with a Stratix IV GX EP4SGX530KH40. I followed the guide to the letter for the SOPC example.

Unfortunately, the PC does not detect the board.

I read on an other forum that the problem may be caused by a x4, x8 misunderstanding from the PC. Indeed, my board has a x8 connector and the PC may recognized her as a x8. The example in the guide use a x4 connection.

I tried to generate a x8 hard ip with the SOPC builder, but you can't choose a x8 with the SOPC builder. :s

BTW: i tried several configurations with the DIP switch but nothing changed.
