Please let me know if that version lets you see your device.
Note that both the snap package and the deb package can coexist on your system without a problem. You can tell which package you're running by checking the command line in chrome://version.
You're using the snap version of chromium, which is strictly confined, and thus won't let you access /dev/bus/ usb/001/ 011 by design.

sudo apt install chromium-browser browser
chromium-
Now, I'm also interested in your feedback on testing a version of the snap that allows access to USB devices:
sudo snap refresh chromium --channel= candidate/ raw-usb- test
sudo snap connect chromium:raw-usb
snap run chromium
Please let me know if that version lets you see your device.

Thanks in advance for your feedback!
