How to setup v-usb on arduino nano?

Question

Arduino

It so happened that I needed a looped input from the keyboard and mouse (fortunately, only keys, it is not necessary to move), and all that is there is 2 pieces of arduino pro mini and arduino nano (all from the Chinese)
Here, according to this manual with a dictionary, I assembled a diagram, it worked:

(Sorry, the link is in this form, I didn’t figure out how to hide it)
But the trouble with the mouse, I found this:
rukodelie-ds .ru/forum/viewtopic.php?t=804
And I connected the arduino already as a composite device mouse + keyboard, there is little left, how to make it work, and not just be recognized?
the simplest is to use arduino leonardo or micro (and they are already on the way), but still want to finish this solution
Emulation on the computer itself, alas, is also not suitable
Ps
I'm very sorry for the design, I'll also be glad to have links to the manual for beautiful design

This is how the steelseries XAI mouse looks now, which can macros, but cannot loop them and a servo controlled by arduino nano, pressing the side button at the right interval, but I myself understand that an adequate device should not look like this

And who said that it will work? At one time, such a device was sold - a "soft" modem. Theoretically, they worked, but in practice they rather taught buyers the proverb "the miser pays twice", because after trying to use such a modem, the buyer again went to the store to buy himself a normal ZyXEL or USRobotics.
