Hi all - I’m stuck on usb (stlinkv2) problem.
I had to switch from windows, which worked fine- except for bug with line endings in debug - so installed/booted kubuntu (20.04).
Everything builds fine, but trying to upload to device fails with “libusb: error [_get_usbfs_fd] libusb couldn’t open USB device /dev/bus/usb/001/003: Permission denied”
Seen some posts on adding user to 'dialout" group which I did (and rebooted), but still same error.
Any ideas much appreciated …
