is my MAP 2nd dead?

i reset the router via button “reset/mode”

“In case you wish to return the device to its original configuration, you can use the RESET button. Hold this button during boot time until LED lights start flashing, then release the button to reset RouterOS configuration.”

when im pluging the cable to the computer on both ports does like some one plug/unplug the cable.

and also USR constanly flashing,even after reset.

is there any solution?

i fixed.
Does anyone know what USR does?

there is no documentation regarding that.
