bluetoothctl doesn't see keyboard but sees phone (which sees keyboard)

When I open bluetoothctl and run "scan on" it finds only my phone (when bluetooth is on). I want to use bluetooth keyboard, but bluetoothctl doesn't see it (unlike my phone).

I changed bluetooth usb adapter to "older one" and it now can see my keyboard. I do the following:

sudo bluetoothctl
power on
default-agent
pairable on
scan on
pair XX:XX:XX:XX:XX 
trust XX:XX:XX:XX:XX
connect XX:XX:XX:XX:XX

and when I enter "connect ..." it says Device XX:XX:XX:XX:XX not available. Even though it's "out of the box" and batteries are new too. The led indicator on keyboard says that device is on "stand by".

update.
I just tried the above thing one more time and now, after "scan on" it gives

XX:XX:XX:XX:XX Name_of_the_keyboard

What is weird, is that last time I tried it, it said

XX:XX:XX:XX:XX XX-XX-XX-XX-XX

i.e. instead of name (same name that my phone sees when I scan for new devices), it just wrote its mac with hyphens.
Then I get the following:

that "[agent] Passkey" line gave me 6 numbers (I replaced them with "*" just in case). Keyboard still doesn't work.

Tried again. Same outcome, also device id is changing all the time.
