Thanks to both for the sanity check. I believe the issue was with file permissions. Running the the following allowed the device to be connected to vitis serial terminal and allowed the device to be discovered in Vivado.

sudo chmod 666 /dev/ttyUSB1

Is your user in the dialout group?

It has been a while since I have used my ZuBoard but looking at the user's guide and schematics confirms my recollection that the FTDI chip on the zuboard is programmed at the factory and ready to go. You should only have to reprogram it if something goes wrong and accidentally overwrite its program. If that happens you have to get a special version of the FTDI programming file, probably from Avnet, to make it work as a Xilinx JTAG cable again.

Also, I am still suspicious of the Ubuntu virtual machine. The special JTAG cable drivers in Vivado really need access to hardware. Virtualization might work for a serial port but not for a JTAG debug cable. I would throw a second SSD into your machine to boot Ubuntu natively and run Vivado.
