Hi there,
Sure here goes specific answers to those questions:
-Have you tried using different hard drives in the unit that does not connect under Linux?
No, I just have tired to unplug some of them with no luck. I dont have other spare hard drives to try.
-Have there been any recent changes on the drives
Not that Im aware of. It just suddenly stardet to not being recognized by the Linux OS at all.
-Is the unit connected directly to a port on the motherboard or some sort of hub? Ideally, it is connected to a port on the motherboard.
Directly to a port on the single board computer (Odroid N2). Tried different ports and cables too with no luck.
-Have you done any recent changes in the operating system?
Just regular updates. Also tried the unit on another single board computer (Odroid XU4) with another OS, same results, no USB detection.
Sure, the serial for the non working Linux unit is: 15497169
Thanks!
