I am trying to reconnect several USB devices (ZTE MF823 modems) on the debian server and sometimes it makes the system crash , this is the output of dmesg -Hw
P.s It is using USB2
Any related information would be greatly appreciated! I have been trying to google all of these error messages without any luck so far. Thank you!
