Not only are the devices no longer available on the host, but no power is drawn by them. Only a reboot fixes the problem. The scanner is the only device that triggers the problem, even when it is the only device plugged in. I have a host of other devices, connected either directly or via a USB hub in my monitor: - keyboard - mouse - logitech brio webcam - yubikey - stream deck - microphone None of these cause any issues. I have tried the following kernels ( packaged for openSUSE Tumbleweed ), and none of them fixed the issue: - 5.15.2 - 5.15.5 - 5.16~rc3-1.1.ge8ae228 The problem does not appear if the scanner is connected when the laptop is shutdown. It seems to have an init phase of about 6-7 seconds (blinking green led) and then stays on. However, it is not detected via lsusb or scanimage -L. The problem does not appear on a desktop class machine ( ASUS Prime X470-PRO/Ryzen 3700x). The relevant parts of the kernel log seem to be: Nov 22 11:53:18 rombert kernel: xhci_hcd 0000:00:14.0: Abort failed to stop command ring: -110 Nov 22 11:53:18 rombert kernel: xhci_hcd 0000:00:14.0: xHCI host controller not responding, assume dead Nov 22 11:53:18 rombert kernel: xhci_hcd 0000:00:14.0: HC died; cleaning up I've initially reported this at https://bugzilla.opensuse.org/show_bug.cgi?id=1192569 and CC'ed the distribution's kernel maintainer. Please let me know if additional information is needed. Regards, Robert Munteanu
