Update of NumWorks Calculator using Chromium & WebUSB doesn't work

[mobluse]

Describe the bug

I try to update the NumWorks calculator using Chromium and WebUSB, but it stops at "Retrieving device infos…". I use Raspberry Pi 500 and the most updated Raspberry Pi OS aarch64, but it is Debian GNU/Linux 12 (bookworm) aarch64. In "View site information" it says "NumWorks Calculator USB device". I also tried "Reset permission" on the USB device and then I reloaded the page and the browser re-detected the NumWorks, but during update it still gets stuck at the same place. I have tested with:
Chromium Version 142.0.7444.59 (Official Build) built on Debian GNU/Linux 12 (bookworm) (64-bit)
and
Version 143.0.7499.109 (Official Build) built on Debian GNU/Linux 12 (bookworm) (64-bit)

When I try an alternative upgrade system https://ti-planet.github.io/webdfu_numworks/ I get the error:
SecurityError: Failed to execute 'open' on 'USBDevice': Access denied.

dmesg:

Screenshots

The error is not on the calculator screen, but is reported in the browser.

To Reproduce

I use this page to update: https://my.numworks.com/devices/upgrade#/start

Here is a video that shows how it should work: https://cdn.numworks.com/65d9d225.mp4
On my Raspberry Pi it stops on page 3/4.

Expected behavior

The update should work as in the video. I believe Raspberry Pi 500 and 500+ are common computers, so it would be good to support them. I reported this to Raspberry Pi, but got no answer yet: https://forums.raspberrypi.com/viewtopic.php?t=393617
Does anyone get update of NumWorks to work using a Raspberry Pi?

Environment

• Epsilon version: 24.8.0 ( bea4886 )
• The platform(s) on which the problem happens: actual device Model N0110
• Computer is Raspberry Pi 500 and the most updated Raspberry Pi OS aarch64, but it is Debian GNU/Linux 12 (bookworm) aarch64.

Now the only computer in my home I can use to update the NumWorks calculator is my Lenovo Ideapad 100 with Windows 10 (which cannot get Windows 11 or 10 ESU even though I tried many guides) and there the NumWorks update works in Chrome. I now have Epsilon version 24.10.0 ( cc796b7 ) on the calculator but update or transferring scripts using Chromium on the Raspberry Pi 500 still doesn't work.

E.g. when trying to send a script to the calculator I get:

Error
We're very sorry but an error occured. Your device screen might have frozen or become black. If so, please unplug your device and press the RESET button on the back of your calculator using a paperclip. In any case, please set up your calculator again.

Setting up again doesn't help.
