Hello and I need help with USB challenges
by Melliw from LinuxQuestions.org on (#56GND)
Hi All,
My name is Willem and life in the Netherlands, fairly new to Linux and the fun around it. so plain and simple I am a NewBie
Being busy right now with a few challenges involving Linux.
I have a HP proliant DL380 G7 server, got it almost for free.
I have installed on it Proxmox and it is running.
The whole thing is a learning centre and playground for me.
In proxmox I create a VM with MineOS so my Autistic 10 year old son can play some minecraft on a server together with his dad.
Next to it I put myself in to a mission mode, I managed to create a Container and docker in Proxmox and the goal is to get Domoticz running on it, well it is running but that is all, nothing else works on Domoticz.
Main problem for now is that I can't get 2 USB devices to be found in Domoticz.
So I have been busy already for some hours over the last few days and just don't get it.
I followed the instructions on the following 2 pages:
https://www.domoticz.com/wiki/PersistentUSBDevices
https://medium.com/@konpat/usb-passt...x-15482674f11d
I did everything but basicly I am already getting stuck on the 1st page.
I do:
lsusb -v | grep 'idVendor\|idProduct\|iProduct\|iSerial'
get my info and I go for:
nano /etc/udev/rules.d/99-usb-serial.rules
I created 2 lines
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", ATTRS{serial}=="DO2XP49U", SYMLINK+="ttyUSB-RFX433"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0658", ATTRS{idProduct}=="0200", SYMLINK+="ttyUSB-ZStick-5G"
I rebooted the server.
And tried for example:
ls -lh /dev/ttyUSB-ZStick-5G
Nothing found
So I did:
mknod /dev/ttyUSB-ZStick-5G c 188 0
indeed a file is created, so I rebooted again.
and did
ls -lh /dev/ttyUSB-ZStick-5G
error file not found.
I checked with FileZilla to get a good overview and, indeed the file is gone.
so tried again and again after reboot the file is gone.
I seriously don't get it.
to me it looks like the folder /dev is every time completely replaced
what am I doing wrong?
