You've definitely got an unusual situation there. You shouldn't have to reboot the Empeg or reconnect the cable. The order that you do those things should be unimportant.

You wouldn't happen to be pluggnig the Empeg in via a self-powered USB hub, would you?

If so, see if the problem goes away when you connect directly to the PC instead of through the hub.
