I troubleshooted the connectivity problems with a windows machine (virtualbox host only adaper --> disabled) to get the our ipad mini retina to show up in Scanect.
disconnected scans work very well.
Once i was able to uplink, the capture through to the PC was VERY slow and lagging. unworkably so.
I'm curious whether this is a problem for others, but have validated that the mini retina is at least visible and connnecting with skanect 1.6
