Zwave and RFXcom problems

i have RFX on the raspberry usb and zwave gpio

RFXcom was working, then i added -Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0" to conf to get zwave to work and now RFXcom doesn’t work
using
/dev/ttyUSB0

/dev/ttyAMA0

Try using -Dgnu.io.rxtx.SerialPorts=/dev/ttyAMA0:/dev/ttyUSB0 instead.

The gnu.io.rxtx.SerialPorts property isn’t used to add serial ports to the list OpenHAB looks at, it replaces the list of serial ports OpenHAB looks at. This really needs to be documented somewhere.

thanks for the help
that worked
