Title:
xhci_hcd ERROR unknown event type 15
Status in linux
I use:
sudo echo "1" > /sys/bus/pci/devices/\:02\:00.0/remove
To remove only the affected PCIe card (mine is a PCIe USB 3.1 controller
card), and
echo "1" > /sys/bus/pci/rescan
To get it back online.
Though it only gets it back temporarily until the event is fired again.
