USB Blaster III VID/PID codes and documenation

Quartus 2025.1 includes full support for USB Blaster III, but the documentation seems to be missing, can we have it? The VID/PID codes are not documented as example, etc..

    Hi,
    appropriate PID codes can be found in usbblaster3.inf and ftdiport.inf from driver folder. They support various combinations of port A JTAG and port B/C/D UART. FT20232H with port UART similar to Arrow USB Blaster II can be selected with PID 6022. I tested the configuration with FTDI FT2232H-56Q Mini Module.

    Seems to be a lot faster than Arrow USB Blaster II.

    Because USB Blaster III driver uses a WinUSB based driver, FT-Prog tool works no longer for EEPROM programming as long as the device is enumerated by the driver. Need to delete the related .inf files or manually erase EEPROM to recover the original configuration.

    Regards
