COM PORT is NOT PRESENT in NI MAX

Hi everyone, i need help. The com port shows in device manager and in NI MAX, but my problem is the status in NI MAX states NOT PRESENT. But when i re-plug or reconnect the USB cable, it states PRESENT. My issue is it happens every time I shutdown or restart the PC. 

note:

what i'm doing is, i'm trying to print in labview using GK888t zebra printer.
