API to detect usb device

Can some one please point to any API or links where i can detect a USB device and other interfaces to t开发者_如何转开发ransfer data into it.I am trying to do this on linux

Take a look at libusb - it's cross-platform.

Can you see your device in the command output lsusb? If yes, then you must check the vendor Id and Product Id of the same.

Probably in Linux there is already a driver available to make bulk data transfer from concerned USB device (your USB device).

You can check this (http://www.linux-usb.org/usb.ids) to verify whether a driver is available or not.

To make your own program and API's, as stated above libusb is a place to start, if you don't want to write a driver for your device.
