You almost certainly can't, they are likely to be custom.
USB is a complex bus, as it has to be to allow many different sorts
of devices to be plugged into it, and "just work".
Someone might be able to reverse engineer one, but from what you post, you
don't have anything near the skills.
There are a couple of ways you might get round this.
Approach sony/... for help.
Dismantle real controllers, and wire your switches across theirs.
As theirs are likely to be proportional, this probably won't work.
If, as I'm assuming, the companies don't release DDKs to let you make
your own controllers, you'd need to reverse engineer it. Probably at
least $5000 worth of work, to document the protocol (it may not be
possible if they are cryptographically signed, but this is unlikely)
Then maybe another $5000 for the prototype.
And then there is the thorny problem that most games probably aren't
playable at all with just bang-bang up/down/left/right controllers,
even assuming a perfectly coordinated player.
At least, you'll need additional drivers for each game, that someone
will need to write.
