Not all devices have USB Host capability. For USB devices to be detected we need:
Android 3.1 or newer (USB Host API support)
Device that has USB hardware.
Compatible Kernel that links the hardware to the API. (Rooting or changing kernel can often solve USB connectivity issues, but only attempt if you know what you're doing).
USB OTG connection.
Sufficient power on the USB bus.
If USB devices are detected, details reported include:
Device Serial Number
Manufacturer String Descriptor
Product String Descriptor
Class, Subclass and Protocol
Number of Configurations
Number of Interfaces
Interface and Endpoint Info
Note the amount of info shown will depend on the USB device and the amount of access allowed.
