Connecting Dualshock 3 to PS3 without USB cable?

So I went round a friends yesterday, taking both of my PS3 controllers. When I left, I forgot to pick up my USB lead. I'm now having trouble connecting the controllers to my PS3 without the lead, as I would normally just plug the controllers in for when to sync with my PS3. I've hit the reset button on the controllers a few times, hoping that would help them connect, but it hasn't worked yet.

I don't believe it is possible, sorry.

Those cables are not very expensive.

Yea, you need that cable. But check around your house/ wherever you live since so many things come with micro USB to USB leads.
