I was going to add an IR receiver to my NUC. Documentation says it has internal header for two USB ports. BIOS even lists the two ports and has them enabled. So I get the parts and everything together. Go to install it and there is no header. Now what? Anyway to resolve this? Thanks.
You must have the very first version of DC3217IYE that shipped (SA#G80097-101). That version did not include the onboard USB header, but it was added with revision -102. You can request a replacement unit from Intel Customer Support. See Service Request Email to create a web ticket.
