Description of problem:
If followed the instruction https://www.home-assistant.io/hassio/enable_i2c/ to the letter.
Tried with multiple sticks in different usb ports.
Clicking the import from USB button just turns it green for 1 second and nothing else happens.
There is a log entry 20-08-19 07:33:47 INFO (MainThread) [supervisor.hassos] Syncing configuration from USB with HassOS
But I2C not available.
The only way to get I2C to work is by doing the updates to the files on the first partition of the SD card via another linux system.

From what I can tell the script responsible to copy the config.txt file is actually copying a source file named boot-env.txt:
https://github.com/home-assistant/operating-system/blob/dev/buildroot-external/board/raspberrypi/hassos-hook.sh#L12

@pvizeli I guess this comes from the fact that the file is named boot-env.txt in buildroot source. It feels to me that config.txt would be more user friendly, but not sure if people use boot-env.txt today already...

Sorry, just realized the script above is a script running at build time. From what I can tell we do not handle config.txt currently?

@ArdescoConsulting I have the same problem.
Did you follow the instruction carefully? Did you create a folder named /modules (the name should contain slash at the beginning)?
Info from here: https://community.home-assistant.io/t/mcp23017-i-o-expander/170486/20?u=misiu

Problem is, that on Windows we can't create folders with a slash in name.
Can this be changed, so both names (with and without a slash) will work?

This was asked in WTH: https://community.home-assistant.io/t/wth-why-enabling-i2c-is-so-hard/219771

Fix I2C documentation
b4669ec 
There is no support of updating config.txt via CONFIG USB flash drive.
Document how to find the hassos-boot partition to configure config.txt
directly on it and use the `hassos-boot` CONFIG method.

Also, instead of using i2c1 use the preferred (according to RPi
documenation) name `i2c_vc`.

@agners I'll check that at home. Thank you for updating the docs!
There is still one wrong link on that page. More details in WTH thread.
