Tiny Connections

A bit of a nerve blipping the same thing that I blipped yesterday, but as the problem is solved and this one is a macro I feel that I have vindicated myself.
 
When you have a nine pin socket designed so that you cannot connect it to the wrong plug/pins you feel very reluctant to connect it to four unprotected pins, even if they do hint that they are USB – but this is what was required.
 
Many thanks to JDO for hosting Tiny Tuesday.
