Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel ? Thank you for your understanding. Thank you Christopher for your feedback. I've read the instructions, they are clear and I'm convinced that following them exactly indeed makes things more efficient for everyone. Also thank your for having edited this bug title and first sentence they look more in the spirit of the instructions. For added confidence, I'm considering first testing the device on another computer that also has USB3 and USB2 ports and/or another distribution using a live media, then updating here then doing the upstream report.
