SW4STM32 v1.13.0
Hi Dieter,
IIRC, it’s due to OpenOCD that now needs a version of libusb that is not supported on Ubuntu releases before 14.04 (at least not by Ubuntu-12.04, the previous LTS). Of course, you may recompile the required libusb release on your system (you’ll know which one by trying to run openocd manually i a terminal), but we can’t advise people to do that...
