In the USBView output above are the lines:
idVendor: 0x0403 (Future Technology Devices International Limited)
idProduct: 0x6010
An FTDI 0403:6010 is a FT2232H/D device, not an FT245B/R. Are you sure you have a Terasic USB-Blaster? I just erased my one, and it reports as an 0403:6001.
Either way, FT_PROG would recognize the device if you have the driver and DLL setup correctly. Note that Windows *must* successfully install a USB-to-Serial converter driver for the FT2232H/D before FT_PROG can actually access it. Check your device manager to see if it has installed a driver.
