I'm using Cyclone IV Transceiver Starter Kit and I got a same problem.

I tried FT_Prog with your FT245B configutation but it fails with message "The current drawn from the USB port must be in the range 0 to 500 mAmps."

This board uses FT245BL with external EEPROM (AT93C46DN-SH-B).

Can you help me?

Can you first just use FT_PROG to detect devices? What does the EEPROM content look like? Is it blank?

I'll check to see if I have a board with an FT245BL on it tomorrow and if I do post the EEPROM contents, if I don't, I can probably make a template that should work.

Cheers,

Dave
