Problem is that the production system where I need to do this is still running 8.0 ... But I got it working with usbconfig -u X -a Y reset, did not work first because I got the wrong device. Not since I'm reseting the correct (non root) HUB I see a powercycle on the USB device, so it works. > Do a power_off command before the parent HUB reset, if the parent HUB reset is > not enough.

Even worse: after trying to reset one of the root HUBS I get: $ sudo usbconfig -u 3 -a 1 reset usbconfig: could not reset device: Device not configured and after this all devices hat are on this bus are no longer visible to usbconfig until the next reboot.
