I performed an upgraded in the web GUI from 9.60 to 9.075. After the reboot, I noticed the following message on the boot screen:
acpid: 1 client rule loaded
unable to initialize libusb: -99
unable to initialize libusb: -99
:: Starting Configuration daemon
:: Starting Confd request queuing daemon
I then tried a fresh install of 9.075 in another VM and the same messages appeared. I'm running UTM as a virtual machine under Hyper-V in bridged mode. If you need me to post other logs, let me know. Thanks.
