I can confirm you suspicions are most likely accurate in Battlefield 4. Hooked my gaming rig into a KVM that I have and also had to use the USB-PS/2 converter and have "exactally" the same issues "W" and "S" keys work for a short period of time (couple seconds) then you have to repress the key. But on the flip side of the coin I also have a USB keyboard (Saitek Eclipse II) which works without a problem in Battlefield 4.
Get a USB keyboard and should fix your problem.
Good Luck!
