Hello @benedictdied ! So, in the end we followed the Docker method to solve the “it doesn’t run on my machine” issue. In our case, we have Ubuntu 24.04 LTS installed and we had to use Canonical’s app catalogue because Docker isn’t directly supported yet by the developer. Docker must be called as sudo, but it works great, here is what I did:
sudo docker run -it --rm -p 8001:8001 -p 2222:22 -e HEADLESS=1 -e HTTP_PORT=8001 -e UPDATE_GIT=1 -e CONFIG_PATH=/config -v ~/Downloads:/config -e UPDATE_CONFIG=0 --privileged ghcr.io/openuc2/imswitch-noqt-x64:latest
At the end it gave us the following text:
INFO: Uvicorn running on https://0.0.0.0:8001 (Press CTRL+C to quit)
We accessed the URL and gave it access. Since the default configuration of the container is to use the example_virtual_microscope.json config file, it worked right away when making use of the web interface from the following domain:
https://0.0.0.0:8001/imswitch/index.html
The file that stores which config .json is going to be used is the one named imcontrol_options.json under the /Downloads/ImSwitchConfig/config path. So, to test my Daheng Camera and stage controller, I switched the parameters to point the correct config file. In this case:
1.- From imcontrol_options.json
{
"setupFileName": "example_uc2_lightsheet_gxipy.json",
"recording": {
"outputFolder": "./ImSwitch/ImSwitch/recordings",
"includeDateInOutputFolder": true
},
"watcher": {
"outputFolder": "/config/ImSwitchConfig/scripts"
}
}
2.- Added the respective .json config file to the imcontrol_setups folder under the /Downloads/ImSwitchConfig/imcontrol_setups/ path.
After this, I rerun the previous steps to activate the docker container and as expected it used the new .json configuration file. The camera does work but the stage controller still doesn’t.
When trying to locate the device with the flashing tool in a chrome based web browser, the window that pops up says that it’s unable to locate the device.
I can confirm this from the terminal’s output too that details the following:
2024-08-22 21:30:03 DEBUG [ESP32Manager -> ESP32] No USB device connected! Using DUMMY!
When trying to use the stage controller from the web interface it throws the following error:

After some troubleshooting, the usb extensor that we used was broken, so we switched to another one and we were able to detect the usb connection from lsusb:
Bus 001 Device 007: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
So I’m not sure why the flashing tool is not detecting it. I also tried switching to other versions just in case but nothing. lsmod shows these entries:
cp210x 40960 0
usbserial 69632 1 cp210x
In the case of sudo dmesg | tail:

And ls /dev/tty* shows a /dev/ttyUSB0 file.
Thank you for your help and time. Looking forward to your comments.
