I had installed v20.6, had some issue with patch display on the Device page but set it aside for a bit.
After reading the recent topics I returned to install v20.7 with the Laboratory tool and it seemed successful. “Device Message: Firmware upload complete.”
However, upon device restart, Wizard entered a mode with solid green LED, no reaction to controls. Does not respond to Device page or Laboratory tool. I found that OWL-MIDI 1 device is missing from system, even when entering Boot Loader mode where it is detected under normal operation.
amidi -l nor lsusb command shows the device in either mode.
