Dear @Bianca, @JColvin
I have the same problem. I used the FT_PROG utility provided by the FTDI to change the driver from "Virtual Com Port" to "D2XX Direct" to test an application that i am developing for my CMOD A7 35T board. After that I changed it back to "Virtual COM Port".
After that my board is no longer recognized by Vivado HW manager. It's state remains unconnected while CMOD is plugged and all power leds are ON.
Before using the FT_Prog utility arty was working perfect in Vivado.
FPGA firmware works good.
Windows 10, Vivado 2020.2
