Similar problem here.
After accepting today the latest updates, I cannot anymore program or debug a custom made board based on STM32F732RET.
The log file is attached. As you can notice, libusb_get_device_list() fails with the error code LIBUSB_ERROR_OTHER.
The hardware connection is ok, the ST-LINK utility is able to recognize the st-link v2 programmer and to read/write the FLASH memory.
The firmware on the programmer has been upgraded to the latest version (V2.J31.S7), I connected the programmer also to slower USB 2.0 ports.
Any help would be very appreciated.
