Naive question from newbie - how to turn on My Book Duo

I’ve recently purchased and installed a My Book Duo drive. It has no on/off switch: I can turn it off by selecting the safely remove option, but having done this I can’t find any way of turning it back on, except by disconnecting and then reconnecting the USB cable. Is there any other way?

Since it doesn’t feature a power switch, a power cycle (Disconnecting and connecting again) is the most direct approach to turn on the drive.
