PinePhone Keyboard update [April 24/04]
(01-24-2022, 07:15 PM)Merc Wrote: One strange thing I noticed which may have just been a coincidence is that when the keyboard battery was turned on the USB-C would not work on the phone until I turned the keyboard battery off. For example I plug in a USB-C dongle into the phone and connect a mouse, the mouse will not work when the keyboard battery is on.

I have an idea it may happen because keyboard's battery powers the phone through pogo pins of the very same power bus where phone's USB connector is also connected (and that is the reason they told not to use both type-c ports together for charging).

So at phone's side it looks to be powered over its USB connector, so probably connected to a charger --> it is a charger connected and not a device.
When a device is connected, phone should supply power (OTG mode) to the device and behaves like a host instead of a device.

I don't know currently how the phone determines if it has to be a host or a device and how to set to appropriate mode (so phone should not power the bus but behave like a host and not a device).

Anyway, currently my keyboard is at local post office where I should go to pick up (they have not tried to come to my house with it).
