Public bug reported: usb devices suddenly die. lsusb shows nothing, only my usb3 hubs. The same bug i had with kernel 4.X and the same bug i had in manjaro. In manjaro xhci_pci was built as module so i could restart xhci_pci using modprobe. In ubuntu xhci_pci is builtin so i restart the pc when it happens. It's a random bug which is only posting error to dmesg, no crash , nothing.
