FTDI is using a specific protocol ("MPSSE") to operate the device as JTAG or SPI interface. It's not compatible with USB Blaster driver.

There's however a way to operate a standard FT2232 (don't know, if it works with FT2232H, too) as a JTAG adapter, that's recognized by the Quartus software. See http://www.alteraforum.com/forum/showthread.php?t=20490

Unfortunately, the solution is considerably slower in SignalTap II operation, while device configuration and indirect JTAG programming are acceptable.
