Hi everybody,
I have never done any usb interfacing with any microcontroller. I want to interface LPC2378 using USB port to PC. Kindly tell me, how can i do this.

Thanks

you need to understand the communication between USB host controller and USB Controller. this page might be helpful to you.

But i should recommend you to first read about USB. you can download documents related to USB 2.0 from http://usb.org

1. Read the USB Protocol by USB Complete by Jan Axelson
2. After that If you are not familiar with drivers in Windows or Linux then goto simple
HID Interface

yes USB Complete is best book to read. go for it..

search if forum maybe you can find it..
