ft2232 support in quartus II

No it does not.

the only support is for the Arrow Bemicro board. when I tried to get the drivers from Altera they refused.

One might want to enable JTAG connection to the FPGA using a standard USB cable, anytime anywhere without the need for programmer.

In my case I didn't have enough pins on the board for both USB and JTAG connectors.

There's a previous thread about the Arrow/FT2232 programmer option.

The driver could be downloaded from arrow (and should be still available there), I don't see a problem to use it at least for personal purposes. The most problematic point is, that's it's considerably slower than USB Blaster particularly in debugging, as reported in the said thread.
