Hi, i have this problem (same Crysis 2).
On the usb i have this: http://h20000.www2.hp.com/bc/docs/support/SupportDocument/c00296394/c00297230.jpg
When USB is attached, i CAN'T open console in Crysis 3 (same Crysis2). My key console for italian layout is "\".
If i remove infrared receiver from USB, restart the Game... console goes perfect.
Can u fix this problem Crytek ? O_O
