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, Vendor ID, Product ID, Manufacturer String Descriptor, Product String Descriptor, Class, Subclass and Protocol, USB Version, Max Power, 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. Note that if you are plugging in a communication device (e.g. microphone/video camera), you will also need to allow audio/camera permissions from the info page first.
