Trackpad froze and lost scrolling

Hi all,

My Macbook Pro Mid-2012 is about two weeks old. From the first day of use, I replaced the original RAM with 16GB Crucial compatible memory, installed a Samsung 850 Evo SSD and transfered the original hdd to the optical drive using an adaptor. Besides, I use a Logitech USB wireless mouse and an external monitor connected using a HDMI to displayport adapter.

Last night I had a really weird problem: the cursor froze for 20 seconds, then it came back without any scrolling capability, and then froze again for several seconds etc. The Logitech mouse was not working neither. I forced a reset and since then the machine appears to be ok again.

What might have caused this? I have created a pastebin with the error messages until the following boot: http://pastebin.com/xfn2xAE6

Also, this is the first hidd.crash file I have on my system report: http://pastebin.com/8Tc0qRKk

Thanks for any input!
