Can't use controls (unpair 0/0)

Hi… After New installation of Retroarch and first run of the app, “upair (0/0) not configured” message appears. And I can’t use all my controls in the app, what should I do? Pls advise, thanks.

You posted this in a development thread, so I moved it. We’ll need more information from you to even guess what’s going on.

What OS/device are you on? What kind of controller are you trying to use?

I can’t match and navigate with PSVita gamepad to RetroArch after new installation to PSVita 2k. “upair (0/0) not configure” appears on the RetroArch menu for my first access into RetroArch. May anyone advise for PSVita gamepad mapping method for new installation? Thanks
