I Wants to know that how the android os is communicating with the storage devices, as because I have two USB Devices from same vendor (ScanDisk) and of equal size (8 GB) and having same File System (FAT32).
Scenario is, I am trying to use those USB Devices using OTG Cable With my MOTO X Play. Lets say USB-A is working fine but not USB-B. Even i Tried to format them using Windows OS to NTFS / FAT32, but still the result is same.
In next attempt I made copy of default folder / directory that usually created by android system to external storage to both USB's, then the Scenario get reversed. with FAT32 / NTFS USB-B works fine but not USB-A.
Surprised? I'm too but I wants to find the reason. Both USB are working fine with other OS like Windows / Linux(Desktop version) as I checked already.
