https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211895 --- Comment #9 from Aleksander Alekseev <afiskon@devzen.ru> --- Here is some additional debug information, just for the record (still on 11.0-RC2). dmesg right after resume: http://afiskon.ru/s/c1/e5cf238331_usb1.jpg dmesg after reconnecting USB adapter: http://afiskon.ru/s/73/9dbafeef9a_usb2.jpg If I disconnect an adapter everything works just fine, usbconfig doesn't ha= ng, etc. If I connect it or (!) any other USB device (a flash drive for instanc= e) back the problem returns. Apparently when I do it code enters an infinite l= oop somewhere in usub_reattach_port and usb_alloc_device procedures. Explains w= hy usbconfig hangs. I will try to reproduce this issue on 12.0 and add a bit more debug output.= I have no experience in kernel development so any suggestions on how else I c= ould debug this issue would be much appreciated. --=20 You are receiving this mail because: You are the assignee for the bug.=
