iOS requires you to enable an accessibility feature called AssistiveTouch [0] to use a mouse with a phone/ipad.
If you already had it on, you could probably use it own the device pretty quick, but it's not enabled by default.

Is this requirement a very recent change?
(I don't have my own iPad with me right now, but I don't recall enabling AssistiveTouch to get the Logitech keyboard+trackpad working.)
EDIT: I looked online and apparently prior to 13.4 AssistiveTouch was required to use a mouse. But now you don't need it if you only want basic mouse functionality.
