I have a question regarding P2416D monitor and it's USB hub that comes with it.

I recently moved my PC one room below, so I'm using quiet long cables now. 5m displayport for my P2416D and 5m USB cable for USB hub that is on my monitor. As far as I know, 5m is limit for USB 2.0, unless I use some kind of powered USB hub every 5m or so.

Now I'm wondering, if it's okay to use 5m USB 2.0 cable from my PC directly to monitor, and then also 3m from my monitor to other devices. Is USB hub in P2416D monitor powered, or is it passive?
