Problem in Kiosk mode in LUBUNTU

Dear Members and mentors,

I am bit new in Linux. We need to deploy HMI for an Industrial controller. The HMI is device is a tablet with Intel Atom Z3745 CPU.

I have installed Lubuntu 18.04 LTS. The HMI is based on HTML/JavaScript. I have called the Index.html page through .xsessionrc (mostly following this page: https://obrienlabs.net/setup-kiosk-ubuntu-chromium/, but I have user .xsessionrc instead of autostart desktop). Everything works well. The HMI has been tested for very long processes and everything works.

Now I have a problem that the Tablet does not mount USB device (flash drives) when the .xsessionrc is running (I can see sda1 if I do lsblk, but no mount point). If I disable .xsessionrc, USB devices are working fine (mounted automatically after insertion).

I have tried to force mount USB using UDEV rule. This also fails. It creates the folder, but USB is not mounted.

Can you please help me? I am totally stuck without any solution in sight.

we need more information about this:

how exactly do the two startup methods differ?
what is in the logs for the two usage scenarios?
how exactly did you "try to force" it?

show us code in code tags, please.
commands issued & full output.
