https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219220 --- Comment #15 from Hans Petter Selasky <hselasky@FreeBSD.org> --- Hi, See "procstat -ak" and which thread is blocked inside USB. When you have a non-behaving USB device which times out and never closes its USB handle from userspace, that will block the enumeration thread, which in turn will block usbconfig. --HPS --=20 You are receiving this mail because: You are the assignee for the bug.=
