STM32F4 USB connection unrecognised
Yes, I have them isntalled. Also I checked the board on another PC that I programmed the STM board before and I also got connection error this time. The power led lights up and programator LED1 blinks red - if thats any indication.
I imagine that udev rules should work on reboot. Alternativelly, I treid restart udev rules command but for some reason that command didnt work, I got: "failed to connect to upstart" (apparetnly upstart was replaced by systemd).
