I have been doing a lot of reading on USB and much is actually bad usb stack implementations on motherboards.
Usb 3.1 is supposedly even worse but we have a single board and have the ability to update usb compatibility in the kernel.
Without doubt USB hubs and adapters are a nightmare and they are not all the same.
Some devices have to go on a host port and will not work though a hub.
Finding what can and what can't seems to be very hard.
We do have a singular device and singular host port (3.0)
I do think though we might be able to find a combination that does work and is fit for purpose.
The chips in these things and the manufacturer / model is really important but we can at least aim for what would be the best and maybe get a working setup.
UASP is actually transparent over a hub and if you get problems its something to do with either the stack or adapter or the hub is just ropey anyway.
Dodgy connectors and power is a huge consideration as we have only 5Vdc of some extremely long and thin poor wiring with some shitty connectors.

I am sticking with usb3.0 and going to aim at a few manufactures and chips.
Sabrent & Anker seem to get good reviews.
The Sabrent usb3.0/sata adapter supports USAP and is a Asmedia 1351 chip and I think that is liked by the Armbuntu guys.

Its the initial post that is puzzling me as actually that unit should work direct to host port.
Maybe try a software update on it? http://www.terra-master.com/html/en/arti...t_713.html
They also have linux desktop software.
2nd post is USB3.1 and that is still problematic and from I have read at the moment 3.0 is a better bet until it beds in.
It is a single disk connected to the host port though Ayufan? It is 3.1 though.
Both are still direct to host port and not multi disk host RAID the terra-master should act like a single disk.

Yes. This should work just fine.
You can consider having a slow backup/sync over USB2.0, but you should be careful using Hubs to provide more USB3-enabled ports as they are mostly unstable and can lead to data corruption.
