Thanks David, so it might be issues with special HW types.
I'm glad you identified quirks to loas uas with to mitigate the issue - this
might help others being affected.
But until I have a local reproducer to debug in-depth I'm not sure I can
do more on the libvirt side (and even then no promises
Thanks for reopening so it can be looked at again, I've subscribed
canonical-server to do so.

I unmounted both partitions and then redirected. Here's the journalctl
output:

Interesting ordering in #1.
It seems the "Failed to sync" lets an I/O hang which is then later reported
failed.
But you could unmount & unbind the device cleanly on the host before you
hot-add it to the guest.
Then for case #1 none of the errors should appear I'd hope.
Do you want to give that a
Oh my bad, Erro should clearly have been Eero but failed to match the

I think I was wrong about the USB speed. I can't find a specific model
number, but the Manufacturer seems to state USB 3.0 for all the drives I
looked at. The host also identifies it as USB 3.0.

Thanks for your feedback Eero,
I have tested USB 2/3 drives on USB 2/3 hubs now - it is not that in in general
a combo of these would fail.
Lets continue to brainstorm what could be the issue ...
I hear from you that your Failing Device is the "Porsche Design Desktop Drive"
and that you say is U
I tested with a USB 3.0 thumb drive and adding that works to the guest
works perfectly.
Here's a shortened lsusb:
Bus 002 Device 002: ID 0951:1666 Kingston Technology DataTraveler G4
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 007: ID 059f:106e LaCie, Ltd Porsche
Hmm, I had one more idea.
I used hot plug all the time (adding the device in virt-manager while the guest
is up), I know that some security handling for apparmor and DAC are different
between hotplug and starting with it.
Let me try to start with the device attached (but using USB 3 controller)

Thanks for upgrading to 18.04 now I can use my system as is for the same
tests.
At least the warning is about a USB 3 device being attached to a slower
(virtual) USB hub.
The default virt-manager/libvirt usb controller is piix3-uhci which is USB 2.0
The controller type can be changed thou, but on
For your comparison here a screenshot with the devices passed through.
I did -not- hit the issues you had which is good for me but bad for helping you.
I'd think that you can avoid:

Hi Eero sorry that you are still affected by issues on your usb passthrough.
But I read that at least the upgrade got you further for bug 1814061.
For the error I see here I at least have an idea what it could be.
I need to grab some HW from my basement after lunch for a test - stay tuned ...
