Connecting serial Port

[zhaijohan]

Hi Oliver,

I have some issues by connecting my USB300 and use this pluging on my rasberry pi.
Can you please tell me, what I have forgotten ?

Output:
`INFO: ESP(1): Using serial port dev/ttyUSB0
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

Comand:

Thanks for any help,

Best regards,

In case you haven't figured it out yet, there is a missing "/" in front of your device definition, it should be "**/**dev/ttyUSB0" not "dev/ttyUSB0". I'd recommend a udev rule to get a static device name though.
