I can't change the connection from "Charging external device" to "File transfer." I have developer mode enabled, and file transfer set as default USB option, but it appears that the SSD is controlling the connection, so I cannot change the mode from my phone. I have replicated this on two SSDs. How can I fix it?
When I connect SSD to perform a backup, I cannot file transfer. How fix?

Construct3944 Did you figure it out?
You could try this app

By any chance, could you share what ssd reader are you using and what file system has it been formated? It could also be silly thing like a cable...
