Hello alltogether,
I just upgraded my NAS to OMV 3.0.75.1. On that occasion I also switched from Bananian (due to the discontinuation) to Armbian 5.25 (with Kernel 4.9.12). At first glance everything seemed fine, until I plugged in my external USB HDD. (Intenso Memory Center 4TB 3,5" USB 3.0). In the "Storage" Section of the Menu an error pops up: "Communication Failure". When clickung on details, no further information show up.
This is the excerpt of the syslog.

What I got so far, is that the HDD (or the casing) supports USB attached SCSI (UAS). However, the bus crashes and reset continously. I have read that is is possible to deacticate UAS and fall back to the BOT protocol. At the moment it would be a possible option. However, I don't know how massive the performance loss will be.
So my question to you is, if this is a known problem and if there are other work-arounds. Is this a general problem with the kernel version? I hope you can help me out here
I am aware that this problem is probably not directly related to OMV. Nonetheless I want to give it a try in this forum, since I have witnesses how many smart people are active here.
Soon I want to connect the HDD via Sata and use ext4 as a filesystem (currently ntfs). But due to a backup via USB I would like to have my USB ports working properly.
Thank you in advance and have a great day.
