I have Arty S7-50 developement board. I used this board for a couple of months without any trouble. Last time, when I connected it to PC through USB connector, Vivado coudn't connect to the board. When I checked the Device Manager, it was seen there as Unknown USB Device. I checked the driver, it was up to date. I have one more Arty S7-50 developement board. I tried that and worked fine.
I can program the board by Platform Cable USB II and works fine. I downloaded FT_Prog software to check if it found the chip. But it didn't. I checked the power pins of FTDI chip, looks ok.

Hello,
I have Arty S7-50 developement board. I used this board for a couple of months without any trouble. Last time, when I connected it to PC through USB connector, Vivado coudn't connect to the board. When I checked the Device Manager, it was seen there as Unknown USB Device. I checked the driver, it was up to date. I have one more Arty S7-50 developement board. I tried that and worked fine.
I can program the board by Platform Cable USB II and works fine. I downloaded FT_Prog software to check if it found the chip. But it didn't. I checked the power pins of FTDI chip, looks ok.
I suspect FTDI chip. Any idea would be helpful.
Thank you
