The Hardware Manager on Vivado is unable to detect the device. The Windows Device Manager recognizes the device but cannot find its driver.
Things that I have tried:
1. re-installing Vivado with “install cable drivers” enabled
2. followed the instructions below from AMD for installing cable drivers on Windows. The log file shows that the driver installed successfully. [https://docs.amd.com/r/en-US/ug973-vivado-release-notes-install-license/Install-Cable-Drivers](https://docs.amd.com/r/en-US/ug973-vivado-release-notes-install-license/Install-Cable-Drivers)
3. Switching the J1 jumper to JTAG
4. Trying to “Update Driver” for the device through Windows Device Manager: I search for drivers in the file location "Xilinx\Vivado\2024.2\data\xicom\cable\_drivers\nt64", and get the message “Windows could not find drivers for your device”
I recognize that my setup is very unconventional which plays a huge factor into this. My goal is to program the device with some HDL. I would also appreciate if anyone has further workarounds.
Specs:
PYNQ-Z2
Vivado 2024.2
Windows 11
MacOS Monterey M1 chip, running Windows using Windows Parallels
The board is connected via USB to a dongle, which is connected to my laptop through USB-C

I had exactly the same issue, but with connecting of PYNQ-Z1. The only thing that helped was downgrade the latest driver by executing of this application with admin rights: C:\Xilinx\Vivado\2020.1\data\xicom\cable\_drivers\nt64\digilent\install\_digilent.exe
Note, Initially I had installed Vivado 2025.1 and its drivers. Most probably the drivers provided with Vivado 2025.1 have an issue with connecting to PYNQ-Z1. So, downgrading driver helps.
