I'm also running into this problem: [ 775.468546] xhci_hcd 0000:02:00.0: ERROR unknown event type 15 [ 780.582774] xhci_hcd 0000:02:00.0: xHCI host not responding to stop endpoint command.

lspci: 02:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller I've tried 4.19-rc8 from mainline ppa - no change. This is on Ubuntu 18.10. Also happened on 18.04. One small note though: On this USB 3.1 controller card, I have connected a USB capture card, that works under v4l. If I use the capture card, with say, Cheese or any webcam application, all works fine, it never dies. Only when the card is not in use it does. I've suspected some kind of power management issue, but power management seems to be off: $ cat /sys/bus/pci/devices/0000\:02\:00.0/power/control on I'm not sure what event type 15 is, but perhaps the card expects a response from the kernel, or some action when sending that event. -- 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/1795763 Title: xhci_hcd ERROR unknown event type 15 Status in linux package in Ubuntu: Incomplete Bug description: i keep losing connection to USB hub plugged in via PCI express usb 3.0 card. dmesg shows the following error.
