Domoticz

I have been trying for days on my raspberry with domoticz (4.10717) to get both my RFlink (from the nodo shop which works fine) and a Z-wave stick from Aeotec working on my raspberry pi 3. If I connect 1 of 2 it works fine but if I try to get both working the other one fails and I have to remove 1 device and restart. I tried all the USB ports but this didn't help either. To rule out shortage of power I feed the RFlink (with arduino mega) separately from my raspberry

Is this a known issue and can it be solved?

This is quite annoying because I no longer have any security because of this. Nobody a clue?

See my setup here: viewtopic.php?f=24&t=28243&p=217062#p217062
My Slave Domoticz has 3 USB port connected. My Master domoticz has 2 USB port connected via a hub.
So it can be solved via udev rules. How to do it is in the wiki.

Thx. I read the wiki udev rules. When I typ in my terminal:
sudo lsusb -v | grep 'idVendor\|idProduct\|iProduct\|iSerial'

I get:
idVendor 0x2341 Arduino SA
idProduct 0x0010 Mega 2560 (CDC ACM)
iProduct 2 Arduino Mega 2560
iSerial 220 7523733353635130A2C1
idVendor 0x0658 Sigma Designs, Inc.
idProduct 0x0200
iProduct 0
iSerial 0

The arduino is my RFlink en the sigma is my Zwave. When I follow the wiki I have to ad 2 rules to Udevrules:
SUBSYSTEM=="tty", ATTRS{idVendor}==“2341", ATTRS{idProduct}==“0010", ATTRS{serial}==“220", SYMLINK+="ttyUSB-RF”

SUBSYSTEM=="tty", ATTRS{idVendor}==“0658", ATTRS{idProduct}=="0200", SYMLINK+="ttyUSB-Zwave"

Problem is this isn't working. I think I misinterpreted the wiki but what is the problem?

there is no need to use udev rules anymore, from the serial port dropdown you should now see serial ports by id names, use this one

hmm ok but then I'm back to the first problem. The zwavedongle and rf usbdevices look like the don't like each other. I can't use them together no. How can I solve this?
