I read some posts, like this one, saying it this not possible to back feed a RPI from the USB sockets.
But I think this is possible. I have two evidences for that:
- This post from Eben Upton (Raspberry CEO) where he wrote « It is now possible to reliably power the RPI from a USB hub that back feeds power… »
- The schemas here. Excepted for revision 1.0, I can’t see any diode or fuse preventing the current coming from the USB sockets to fully power the RPI.
So, am I missing something?
