Actually, I don't know if you know about it but I have writtem a post on my blog mainly about how to circunvent the fact the EFI partition doesn't exists on your disk (ours is a Mac Pro 2011 *first season*) I'm not sure if a Mac Pro 2018 can eventually boot from legacy..
If you can.. clear your EFI partition exists. One more idea I came out with is looking to your log (and I seldom evinced anything good) .. sd0 at scsibus1 targ 1 lun 0: <SSK, USB3.2, > removable sd0: 119275MB, 512 bytes/sector, 244275200 sectors xhci2: command ring abort timeout uhub2: device problem, disabling port 1 xhci2: command ring abort timeout uhub2: device problem, disabling port 2 xhci2: command ring abort timeout uhub2: device problem, disabling port 3 xhci2: command ring abort timeout uhub2: device problem, disabling port 4 xhci2: command ring abort timeout uhub2: device problem, disabling port 5 xhci2: command ring abort timeout uhub2: device problem, disabling port 6 xhci2: command ring abort timeout uhub2: device problem, disabling port 7 xhci2: command ring abort timeout uhub2: device problem, disabling port 8 xhci2: command ring abort timeout uhub2: device problem, disabling port 9 xhci2: command ring abort timeout uhub2: device problem, disabling port 10 xhci2: command ring abort timeout uhub2: device problem, disabling port 11 xhci2: command ring abort timeout uhub2: device problem, disabling port 12 xhci2: command ring abort timeout uhub2: device problem, disabling port 13 xhci2: command ring abort timeout uhub2: device problem, disabling port 14 xhci2: command ring abort timeout uhub2: device problem, disabling port 15 xhci2: command ring abort timeout uhub2: device problem, disabling port 16 xhci2: command ring abort timeout uhub2: device problem, disabling port 17 xhci2: command ring abort timeout uhub2: device problem, disabling port 18 xhci2: command ring abort timeout uhub2: device problem, disabling port 19 xhci2: command ring abort timeout uhub2: device problem, disabling port 20 xhci2: command ring abort timeout uhub2: device problem, disabling port 21 xhci2: command ring abort timeout uhub2: device problem, disabling port 22 xhci2: command ring abort timeout uhub2: device problem, disabling port 23 xhci2: command ring abort timeout uhub2: device problem, disabling port 24 xhci2: command ring abort timeout uhub2: device problem, disabling port 25 xhci2: command ring abort timeout uhub2: device problem, disabling port 26 Pay attention from my experience a usb3.2 disk requires a fully compatible system with ver 3.2 otherwise you end up in a situation similar to what you just described, about speed I mean. I am just speaking looking your specs, *someone more knowlegiable* than me can eventually expand against 7.6.
