OK, did some digging, and have a bit of good news\bad news for users of USB-C.
First, the good news. If the connections are both USB Type-C, and you have a proper quality cable, it should just work. There is no longer any such thing as OTG (unless you are connecting down to a Micro or Mini or Type-A or Type-B plug). With the reversible connection and e-marker cables, the specification clearly calls for the host and peripheral to negotiate a proper connection in a protocol they call DRD.
Now the bad...I'm struggling to find quality Type-C cables AT ALL, let alone ones with a right angle plug. Here's the problem. USB Type-C has undergone two major and a number of minor revisions since it was introduced. Further adding to the confusion, some manufacturers needed functionality that was addressed in later revisions, but in their haste, created one-off situations. It's been mostly cleared up now, but the damage was done. If you look on Amazon, the number of options for straight Type-C to Type-C cables is boggling. Version 2.0. Version 3.0. Version 3.1. Gen 1. Gen 2. 2 ampere vs 5 ampere. Thunderbolt capable. eMarker. USB Power Delivery.....ugh!
The variations are huge, and even worse, the manufacturing quality of most of these is just simply terrible. Remember, we went from relatively few conductors (4, actually) in previous versions of USB to eighteen (18!!!!) in USB 3.1 Type-C. From 5 pins to 24. In between there is USB 2.0 Type-C, with six conductors. Confused yet? Here, take a look at Wikipedia has to say about
USB Type-C.
The hopeful news is that if you get a good cable and your devices support the latest USB Type-C and 3.1 specifications, life is good. Data rates are huge, signal quality is assured, power is transferred nicely and the format can support anything from multiple monitors to fast charging smartphones.
-----------------
TL;DR-> USB Type-C is a frightful mess. Here is a
link to a good cable. Let me know if you find one that has right angle plugs. Cheers!
