OpenOCD not working under System Workbench
Openocd in SW4STM32 also detect the stlink version (since a few versions of the ide, so before openocd did the change).
I don’t know if on Mint18, this is the same udev rules mechanism for declaring stlink usb pids as on Ubuntu for example.
It seems yes, looking on web quickly.
Or maybe you are using an old STLINK V1 ?
