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. This is being printed to stdout buf[0]: 1 buf[1]: 16 buf[2]: 17 buf[3]: 24 buf[4]: 38 buf[5]: 157 buf[6]: 80 buf[7]: 6 buf[8]: 25 buf[9]: 132 buf[10]: 57 buf[11]: 32 buf[12]: 126 buf[13]: 128 buf[14]: 17 buf[15]: 173 buf[16]: 33 buf[17]: 10 buf[18]: 53 buf[19]: 9 buf[20]: 68 buf[21]: 182 buf[22]: 68 buf[23]: 3 buf[24]: 204 buf[25]: 20 buf[26]: 74 buf[27]: 2 buf[28]: 35 buf[29]: 33 buf[30]: 196 buf[31]: 0 buf[32]: 10 buf[33]: 132 buf[34]: 56 buf[35]: 203 buf[36]: 16 buf[37]: 206 buf[38]: 17 buf[39]: 132 buf[40]: 23 buf[41]: 64 buf[42]: 79 buf[43]: 112 buf[44]: 136 buf[45]: 74 buf[46]: 25 buf[47]: 88 buf[48]: 32 buf[49]: 79 buf[50]: 66 buf[51]: 50 buf[52]: 214 buf[53]: 144 buf[54]: 138 buf[55]: 32 buf[56]: 17 buf[57]: 96 buf[58]: 1 buf[59]: 200 buf[60]: 152 buf[61]: 230 buf[62]: 25 buf[63]: 86

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
