Subj : USB port issue -follo To : Ky Moffet From : Barry Martin Date : Sun Mar 08 2020 10:51:00 Hi Ky!

A static discharge to the case could still jump to the USB section, just looks like a different/another problem. Right now trying to figure out where to begin other than an almost complete rebuild. ...Suppose the first thing would be to open the case and see if anything looks wrong. Let things 'sit' a while and see if I remember anything which didn't seem to go as should during construction -- like something having to be forced. ¯ ® ¯ Barry_Martin_3@ ® ¯ @Q.COM ® ¯ ® ....
