USB is a one master, multiple slaves system. Two slaves can't communicate directly neither can two masters.
In the default state both 2040 boards will be slaves. You need one to act as a master and the other to act as a USB device that the master knows how to talk to.
I'm not at all sure how easy that is in upython.
Franlky, it'll be much easier to use a UART on each end.
