Happened to connect a USB hub before dealing with the Void drive. Noticed the USB socket where the Void drive was connected had a black plastic contact carrier and another socket had a blue carrier. Blue is USB 3. Black isn't? So plugged the USB adapter with the Void drive into the blue socket. Voila; Grub was able to boot the Void system reliably. Spent the better part of a day investigating when a USB plug just needed moving. =8~/ In case anyone is interested, these topics remain. * Why does the ThinkCentre have differing USB sockets? * With the adapter labeled USB 2.0, why is connection to a USB 3 socket necessary to boot the external system? * The Grub2 manual could explain more about USB and the nativedisk command. In fact, the manual needs work in many places. Regards, ... P. -- VoIP: +1 604 670 0140 work: https://en.wikibooks.org/wiki/User:PeterEasthope
