Problems with new installation

I have recently had to reinstall my system due to my micro SSD card going on the blink.
When I restart the new system it appears to continually restart.

Any insights would be more than welcome


cmx@Pi3SOS:~ $ cd /opt/CumulusMX
cmx@Pi3SOS:/opt/CumulusMX $ dotnet CumulusMX.dll
Cumulus MX v.4.1.3 build 4028
Working Dir: /opt/CumulusMX/

Cumulus running at: http://localhost:8998/
http://127.0.1.1:8998/
http://192.168.1.107:8998/

Open the admin interface by entering one of the above URLs into a web browser.

Others may know better, but first, if you are uploading to website using the PHP method have you copied the PHP Upload secret: code in your \webfiles\upload.php file and then FTP that file to your website?

I think this is yet another FO usb station that does not work due to the ”Stream open failed” error. I think no-one has resolved this yet.

It is a permissions problem.

If I run CumulusMX as root it can read the HID device OK. As a regular user it fails.

I have tried adding a new rule file to /etc/udev/rules.d/
with the contents:

Code: Select all

SUBSYSTEM=="usb", ATTR{idVendor}=="1941", ATTR{idProduct}=="8021", MODE="0666"
and adding a new line to the existing 99-com.rules file

Code: Select all

SUBSYSTEM=="usb", GROUP="pi", MODE="0660"
Either of which is supposed to fix this, but even after a reboot (incase "sudo udevadm control --reload" didn't work) my regular user "pi" on an old system still had not access to the HID device.

Any Linux gurus got any more ideas?

I also tried changing the file permissions ton the device itself (/dev/usb/hiddev0), still the same problem.

Try adding the pi user to the wheel group.

I tried using "plugdev" as the group in the udev rules as recommended elsewhere - and the pi user is a member of that group by default. No workie.

Add the pi user to wheel group - "The group "wheel" does not exist.

OK fixed! The rule syntax is slightly different from the original source I looked at.

To fix this I did the following (all as root/sudo)...
  1. Create a new udev rule file:

    Code: Select all

    /etc/udev/rules.d/50-usb-cmx.rules
  2. Add the following content:

    Code: Select all

    SUBSYSTEM=="input", GROUP="input", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="1941", ATTRS{idProduct}=="8021", MODE:="0666", GROUP="plugdev"
KERNEL=="hidraw*", ATTRS{idVendor}=="1941", ATTRS{idProduct}=="8021", MODE="0666", GROUP="plugdev"
  3. Unplug the stations USB cable
  4. Run the command

    Code: Select all

    sudo udevadm control --reload-rules
  5. Plug the station USB cable back in
  6. Run Cumulus MX as a regular user - now works :D

Many thanks Mark, that seems to have done the trick although I haven't a clue what is going on!

Can you make this a bit simpler for raspberry pi noob, how to get root/sudo ??

Either

Code: Select all

 sudo su -
and then run the commands, or prefix every command with

Code: Select all

sudo

Hmm, get the following error?
sudo: /etc/udev/rules.d/50-usb-cmx.rules: command not found
Any ideas?

You're creating a new rule which is stored in a file. So you need to do

Code: Select all

sudo vi /etc/udev/rules.d/50-usb-cmx.rules
to create the file and open it in a text editor, add the rule in the file and save it. With vi/vim you hit ESC and press

Code: Select all

:wq
to save the file and quit the editor.
Alternatively, create your file on your laptop/pc and upload it to your pi. - but you will need to change ownership and permissions if you do it that way, so might be best to brave the vim command line editor.
