Hi! Could anyone please help correcting my script? I would really appreciate that, I've been frustrated by this for hours. It works for my mouse but not the keyboard: 

# Switch MX Keys Mini to Channel 1
hidapitester --vidpid 046D:B369 --usage 0x0202 --usagePage 0xFF43 --open --length 20 --send-output 0x11,0x00,0x09,0x1E,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00

# Switch MX Master 3 to Channel 1
hidapitester --vidpid 046D:B034 --usage 0x0202 --usagePage 0xFF43 --open --length 20 --send-output 0x11,0xFF,0x0a,0x1b,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00

This is what hidapitester --list-detail returns for the devices:

I still don't completely understand the whole thing but I made it work by using this script:

# Switch MX Keys Mini to Channel 1
sudo hidapitester --vidpid 046D:B369 --usage 0x0202 --usagePage 0xFF43 --open --length 20 --send-output 0x11,0x00,0x09,0x1e,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
# Switch MX Master 3 to Channel 1
hidapitester --vidpid 046D:B034 --usage 0x0202 --usagePage 0xFF43 --open --length 20 --send-output 0x11,0xFF,0x0a,0x1b,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x000x11,0xFF,0x0a,0x1b,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00

Because sudo commands require a password I also had to modify visudo by running this command:

export EDITOR=nano
sudo visudo

and adding this line at the end to the file, then saving it: username ALL=(ALL) NOPASSWD: /usr/local/bin/hidapitester
