Hi Lois,
I am only addressing this to you because you have answered a few earlier posts from people with the same problem that I have. I purchased the DC3217IYE and despite the specifications listed on the Intel website, my NUC does not have an internal USB header. I can see where it is supposed to be - there are ten little holes next to the front panel header, but no header for two extra USB ports. Like others have posted, I plan to put an IR receiver on that header. Please let me know what I need to do to get this sorted out. Thank you for your help.
Cheers,
Spencer
