-- BC test
+- BC test. I'm not sure what I had in mind but there were too errors: micro-B D- and D+ are shorted on the board (thus no way to detect the short in the plug), D-/D+ on the test would be left floating on plug with BC (thus would not turn the LED on)
+- VBUS test. On cables with ground wire, but no VBUS wire (such as A-C cable with not all GND or VBUS pin in C plug), the power ground would pull down VBUS through LED D1A for host A just enough to switch on Q1, lighting up LED D1C LED for host C
+- CC test: only for *-C cable. C to micro-B would also trigger it
