USB Serial Port Problems

I have a D21G connected a computer running Ubuntu 18.04.  I am using the USB serial connnection to communicate.  However, I have noticed that the usb serial connection will dissappear after several reboots of the computer without a power cycle of the D21G.  It usually takes about 12 to 15 reboots.  Is there additional handling that is required on either end to properly close the connection?
