Behringer X-touch and USB plug'n'play Cubase LE elements 8

Hi there. I have been using Cubase LE elements 8 with the Behringer X-touch but have found that if the unit is disconnected, only a full reboot of cubase will allow re-connection. I have read that in Cubase 9, it has USB plug’n’play support. Does Elements 8 have this also or is a reboot of cubase the only way to re-connect? I have tried pushing the reset device button but it does not connect. Any help is greatly received.
