Installing sys-usb is periodic time for anyone. In order to fully install sys-usb, delete the sys-usb then reinstall it at daytime. This way, it can install it properly. If this happens again, then you need to reconfigure your server to allow that happen. Why? Installing sys-usb might need go out to the internet to the server for the scripts. Otherwise, I will tag @unman, @deeplow, or @Sven for that troubleshoot.
