USB HID Mouse Driver using LPC2148

Are you working on Keil HID example?

Then, you don't need to swap entire descriptors.
Replace just the report descriptor.

I see some errors on the config descriptor set in above post, for example, wTotalLength field. But it's pain to examine the figures without any comment for the fields.
I recomend you to recover the original descriptors from the example.

For other change,

demo.c

BYTE InReport[3];      /* HID Input Report - 3 bytes for mouse */

/*
 *  Get HID Input Report -> InReport
 */

void GetInReport (void) {
  //
  //  Fill InReport[]
  //
  //   InReport[0]    mouse buttons, bit 0: left, bit 1: right, bit2: middle
  //   InReport[1]    X axis relative movement
  //   InReport[2]    Y axis relative movement
  //
}

Hello guys,

I am a first timer with USB and like many others, VERY CONFUSED.

To start with, i have downloaded the example code for USBHID for LPC2368 and it is not working, leading to more confusion but most of them are conceptual and here are a few of them :

1. How will the code call the functions usbcore.c ?

2. How will the code initialize the descriptors and endpoints ?

Any help will be greatly appreciated.

Thanks.

Don't you think you should start with a new thread, instead of hijacking someone elses?

Yes, I should have.

Apologies for that.

Can you please tell me how to start a new one ?

Thanks.

Got it ..

Thanks.

Please Help Tsuneo !

Sorry for posting here again.
