PS4 mouse and keyboard

[Grizzlebeard]

I use a Logitech mouse and keyboard set that utilizes one USB stick and haven't had any problems with either PS3 or PS4. Granted, it's rare I'll have something plugged in to the second USB port.

I've got a USB hub plugged into my superslim PS3 so I can attach a headset, the webcam, a PSP charging cable, and a wireless keyboard dongle all at the same time, and haven't had any problems so far. >_>b

I've played DUST 514 using said wireless keyboard and a wired mouse and it seems to go okay?

Maybe there's a difference between PS3 systems, or maybe it partly depends on how much power your devices draw. My wireless keyboard has its own batteries, and I suspect a big gaming keyboard with glowy lights would probably pull lots more power.
