Generic ST-Link V2 Not Resetting Target?
I had the same problem! If you take a look at the PCB you see the NRST signal is messed up, meaning it is not connected to PB0 of the stm32F103 MCU in the programmer - instead it is connected to the "other side"(interestingly to a totally mirrored position of the MCU).

What I have done: 

Removed the resistor R18 which connects the NRST connector pin to the wrong pin on the MCU. Then with a simple resistor 10R-100R I connected to NRST connector pin to the PB0 of the MCU (number 18 of the QFP 48).

After all, it woks just fine, for Trace support the SWO pin should be wired too
