I don't think OpenOCD's USB usage is such that the used driver has any noticeable effect. In another project where the FT2232 was used as a synchronous serial port I had no troubles reaching sustained transfer speeds of over 120 kilobytes/second using libftdi (the remote device's serial port was the limiting factor). This was on a 1.4 GHz PPC Mac.
