What is this socket on the side of the Forma? It is a bit wider on one side so I thought it should work with the older USB cord I've been using, Micro-B, which it sort of does but the connection is unstable and Windows makes the disconnect and connect sounds several times while it's connected.
Then I looked at the USB cable that came with the Forma and it's not wider on one side, and it looks like the newer USB. But I have a newer USB-C cable and that connector on it is wider than the Kobo's.
The Kobo's cable gives me a solid connection so I'll stick with it. I hope I haven't damaged the socket by using that other cable.
Here's a picture of different USB connectors. The Forma ereader's connector is Micro-B, the second one. But the cable looks like it's Micro-USB AB, the first one.
Here's also the wikipedia article, scroll down to the "Receptacle (socket) identification" table. It looks like the Forma's cable is Micro-A but it's rounded, not rectangular like in their picture.
I'm confused.
