 The circuit was tested with a 74HC244 IC and TJTAG 3.0.1 and 3.0.2.1 on a few machines with success barring issues with using one 74HC244; replacing it with another 74HC244 from the same set fixed the recognition issue. This is why a 74HCT244 is recommended with this circuit.

+This same circuit on a perfboard - prototype unit before the final PCB design... photos aren't as clear; my long retired LG G7 ThinQ was better for this.
+Also, the jumpers for switching 3V3/5V0 exist because I do not have a DPDT switch on hand.
