Do you know whether or not the USB-Blaster actually works?

Rather than programming the MAX CPLD, try verifying its JTAG ID using the Quartus debugger.

Some of the Rev C USB-Blasters came with a flex cable while others come with a ribbon cable ... I recall problems with one of those, but forget which ... I have USB-Blasters with both and they work fine for me.

Cheers,

Dave
