That makes sense. How can I check that?

Which "configuration" are you referring to?
Something like this? /sys/devices/12110000.usb/usb3/3-2/bConfigurationValue

I'm happy to try any command line you give me.

If that command works, I can write the udev rule for future testing
with these devices.

Ok...just need one more bit of guidance from you and this will be
resolved I think.
