@bybeu, USB Emulation: This allows USB devices (keyboard, mouse, USB drives) to operate in BIOS / DOS.
USB Powershare: This allows USB ports to provide powers in sleep or power-off, depends on hardware designs. This consumes some battery power in sleep or power-off USB Wake Support: This allows / disallows USB devices to wake up systems from sleep. External USB Ports: external ports are ports you can connect devices to. "Internal" ports are ones connecting to built-in devices like webcam, sd card and so on. You can disable "USB emulation and USB powershare" if you are not using them. A problem like this can be the results of (1) system sleeps but is waken up immediately, or (2) device driver fails to put hardware into sleep. Comment #3 (and "USB wake up support) is to address (1), and #22 is to verify whether new drivers in kernel can address (2), since are are running on much older kernel 4.4 You can boot to Ubuntu 20.04 (kernel 5.4) live with USB and suspend, if you don't want to install kernel package, or try kernel 5.8 as in #22 if you feel comfortable with installing kernels. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1887564 Title: Laptop XPS13 can't sleep Ubuntu 16.04.6 LTS when USB3 device is/was attached. Status in linux package in Ubuntu: Incomplete Bug description: (Ubuntu 4.4.0-185.215-generic 4.4.224) If I plug a USB3 device on the USB3 port then I can't send the laptop to sleep. (this happens with audio interface UMC404HD and Gbit Ethernet Adapter Trendnet) Instead it cancels the sleep process: Jul 13 10:24:22 xps kernel: [318785.373269] video LNXVIDEO:00: Restoring backlight state Jul 13 10:24:24 xps kernel: [318785.375145] PM: Syncing filesystems ... done.
