Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd like to suggest you refer to the usb_host_msd_fatfs in SDK library and you can download the SDK library via the following link.

Hi Jeremyzhou

Thanks for reply. What it supposse to happen? I mean; I saw a message "host init done" but when I connect the USB device, nothing happened. What it should happen when I connect the USB pendrive? I had tried with almost all examples but nothing happened, maybe I'm doing something wrong. I attach a picture about how I'm connecting the device.

Best regards

Hi Oscar Niño,Fig 1 illustrates the run result, and Fig 2 represents the hardware attaching.
On my site, the usb_host_msd_fatfs demo works well.
In the attachment, it guides the developer how to get started with the demo.
