The drive that was giving me this problem failed. I got a replacement (which is notionally the same model, with the same USB ID 0781:5581), and, on kernel 4.15-22, under Xen, the new drive seems to work fine in USB 3 ports.
However, I also tested with the latest v4.17 kernel from the given link (4.17.0-041700.201806041953) That kernel does not boot under Xen where I run my system (it seems to suffer from https://bugs.launchpad.net/ubuntu/+source/linux- signed/+bug/1777338). When I load it outside of Xen, it does not mount my home directory, because it is on a ZFS disk and the provided builds do not seem to include ZFS support. It also does seem to work fine with the drive, but it has other substantial problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775487 Title: Sandisk Ultra USB 3.0 Flash Drive doesn't work in USB 3 ports To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1775487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
