Error: RFLink: Error opening serial port!

Suddenly got a problem. I have tested to change USB port on the Raspberry Pi where the RFLink is attached.

works for me on latest beta domoticz. check your settings for rflink under hardware. make sure you'we selected the right port. else check power supply

[ottoangel]

Under hardware the port was empty. Shouldn't it be named something like /dev/ttyUSB? See picture.

Your system needs reinstall... Or better voltage

It was the USB cable that was the problem. Now it works again. Thanks for the help.
