I replaced the go and ident.cfg files and all seems functional at this time. That certainly explains why I was seeing the "tower" prompt earlier.
I suspect you are right about the thumbdrive. I have had a few issues seeing:
unable to enumerate usb device
I will look into replacing it with another device. Thank both of you for your assistance.
I upgraded to 7.0 this morning and seeing the following if attempting to access gui remotely or even locally:
500 Internal Server Error - nginx
Symptoms sound similar to the following, but don't recall ever touching the go script.
