If you want to get more information about what's happening at the USB level, you should use usbmon (see Documentation/usb/usbmon.txt in the kernel source for instructions). It will tell you what commands are being sent to the drive, but not which program is responsible for sending them. Still, you can use it to compare the different Ubuntu releases.
(Hint: If you do collect a usbmon trace, it helps to unplug beforehand as many of the other USB devices as you can, to prevent the data streams from getting all mixed together.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1733068 Title: Unmounted USB drives wake up on 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1733068/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
