I wonder, why you want to use a microcontroller for this purpose. A plain FT2232 USB interface device can act as a USB blaster replacement, using the BeMicro driver, as discussed in this thread:

A principle option to replace the original USB Blaster would be to emulate the FTDI FT245 device, and the hardware acceleration built into the USB Blaster CPLD.

To connect your own USB driver at the PC side, you would need a documented interface to the Altera JTAG server, which obviously isn't available.
