Comment 84 for bug 1810183

I used this command :
for f in /dev/i2c-*; do sudo i2ctransfer -f -y ${f:9} w13@0x15 0x05 0x00 0x3d 0x03 0x06 0x00 0x07 0x00 0x0d 0x14 0x03 0x01 0xad; done

And I get theses errors :

Error: Adapter does not have I2C transfers capability
Error: Adapter does not have I2C transfers capability
Error: Adapter does not have I2C transfers capability
Error: Sending messages failed: Input/output error
Error: Sending messages failed: Input/output error
Error: Sending messages failed: Remote I/O error

I've tried to replace f by 1 to 6 to find what is the unique command that is working for me... it seems I don't understand how to do that.

Can somebody explain me ? I just want to find the right command for my computer to help all the people who have the same computer to illuminate it. Just for the eyes actually but so nice !
