System Workbench for STM32

Ok, v1.10.0 is the latest version.

Driver is ok and since you can use STLink utility, it is ok on this side.

I said to not let an STLink connection active on another software (like Stlink utility) or another ide like co-ide because you can only have 1 STLink connection active.

Reboot the disco (and the PC) and try again.
Win 7, 64 or 32 bits ?

The error message "open failed", you get it when no stlink board is connected.

And if i let a STLink utility connected, i have the libusb error access added on the message:

Info : clock speed 1800 kHz
Error: libusb_open() failed with LIBUSB_ERROR_ACCESS
Error: open failed
in procedure 'init'
in procedure 'ocd_bouncer'
