You need a correct power supply to not provide power to the Vero via a Vero’s USB port.
Some time ago @sam_nazarko provided some links how to order them within the osmc shop, see his post

Other way would be to get one somewhere else, specification: DC 5V, min. 2A, center positive, coaxial power connector male with OD 5.5mm and ID 2.1mm
Addition: But this link was created BEFORE brexit!
