BTW, on dfly bsd the same sequence of events is causing full controller reset, which is clearly bad, as USB devices attached (to the laptop) on xhci0 will vanish. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-usb@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
