I have a UR22Mk2 which I use with a MacBook Pro. I power the UR22 by plugging its USB cable into a USB slot on the Mac.
My problem is that whenever I’m through using the UR22, when I unplug the USB cable from the Mac, the Mac reboots and generates a warning that something caused the reboot. I get tired of this, but I don’t want to leave the UR22 turned on all the time, and there is no separate on/off switch.
Also, if I turn off the Mac, it won’t turn off, simply reboots if the UR22 is still plugged into it.
Driving me slightly nuts. Any ideas how to solve this? Would an external power supply solve it?
