[syslinux] USB keyboard problem

The strange thing is that I have Legacy USB enabled on the BIOS.
And I have downloaded an pxelinux.0 version from pxes.sourceforge.net
and that version works.
The last one (that I downloaded from syslinux site) doesn't work.
Must I make any thing in pxelinux to work?
The machines are Intel dot stations, kind of thin clients.
