Created attachment 279019 [details] Sabrent logs collection Hi, I am trying to use an external SSD drive ( Samsung 850 Pro 256GB ) with Linux in it, and booting it was an external USB drive. The environment itself works totally fine and I got not critical issues using it as a daily driver. Although sometimes, the system "hangs" very rarely, but in an annoying fashion that makes a bit sluggish the experience. Initially I thought as I'm using an USB 3.0 adapter, that maybe the UAS driver was buggy, but at my own surprise I found out actually that the UAS driver is not used at all, although the adapter supports it fine. I am currently using it on a Dell Latitude 7480, and when I use `lsusb` I see that the device is recognized as `JMicron JMS561U` which, by spec, supports UAS ( see http://www.jmicron.com/PDF/brief/jms561u.pdf ). I am wondering if this device was already tested by anyone of you already, and if not, if I can be a tester for a patch to enable UAS on this adapter. Thank you very much for the support, as an attachment ( sabrent-uas-logs.md ) you may find all the logs you may need to further help me debugging this. Best regards, Julian

Please bring this issue up there, if it is still a problem in the latest kernel release.
Thank you and sorry, I wasn't aware of that mailing list. Feel free to close this ticket. I just sent an email to that mailing list. Best regards, Julian
