.
Just starting with PYNQ on the Cora Z7 board and have downloaded the 3.1 image from GitHub - devsaurus/Pynq-Cora-Z7-07S: SD card image and base files for building PYNQ on Digilent's Cora Z7-07S · GitHub
The system starts OK and I can get python running etc.
But the USB is not working. Command lsusb shows no devices even through there is a dongle in the USB slot. Also there is no device in /dev/…
Revision is
Release 3.1 (Carlisle) 2025_10_03 19ed17d
Board 2025_10_03 20c6bce
Note we have had the USB up and running in other releases of Ubuntu.
