UPA USB CLONE ISSUE
Bought a China clone UPA 1.3 and it installed correct with drivers. Read 93c46 o.k but can't read any Motorola mcu always says device is not responding and 1 error is found even when it checks out correct with voltmeter. Run hardware test with sometimes 4, 5, or 6 failed test. Please any suggestions?

4, 5, or 6 failed test.
Something is wrong with inverter MC34063A. First check soldering. |

RE: UPA USB CLONE ISSUE
the Test result in your attachment is only for 3.3V, can you show the result of 5.0V testing?
