after the upgrade to Catalina I have some problem with the USB hubs. I have three USB hubs (all working fine before the upgrade) that when plugged they are recognised once every 10/15 times. If I plug the usb hub and then restart my Macbook (12", USB C port only) they are working fine. I can't keep logging out or restarting each time I need to connect one, and I have already tried to restore my Mac without using any backup (huge waste of time, really ). So I am looking for a way to kill/restart the USB service manually via terminal. The hubs are HDMI, Ethernet and USB hubs, each feature works fine without issue, just the USB doesn't work until restart. There's no driver or anything to install as they always have been plug and play. I know that Catalina has removed any support to 32bit application but again, there's no software that was needed. It's not a matter of kext because as I said if I restart my Mac everything is working fine.
Anyone aware of how to kill restart the usb kext/process?
ps: Reset Pram didn't help :(
Thank you very much
