The EX2 got the same Problem like the other had (all except EX2 got an update on 29/3/16 for this USB fail)… If there is a large number of files the Backup doesn’t finish, it stops and the USB Harddisk will go into power save mode after. The OS says its still working and stays at the % till you end it.
I don’t know why the EX2 is the only device which didn’t get updated. There is all over near the same OS on it… a feature more or less.
