Hi,

does the issue persists with the latest committed version, that uses the libusb backend?

Thanks.

Sorry , i missed this comment.
I just checkout from git and it is not working at all.
It is not segfaulting anymore, but the relay is not being opened/closed.

Hi,
that output was a debug print that should have been removed. We just did a new commit with the fix.

But the relay not switching is strange. If you run the following command:

ykushcmd -u a

the external ports LEDs (4 LEDs) are turned on?

Best Regards
