LPC2378 :Integeration of USB CDC with Ethernet Http Demo code

Murthy r

Hi Friends,

I am using the LPC2378 processor.

I have the USB CDC example code and Http Demo example code.

Both codes are working well in alone.
i want to integrate the USBCDC code and the Http code.

so i integrate the both code and connect the USB cable with the PC.

The USBCDC code is working well.

The problem is when i connect the Ethernet LAN cable i am not able to access the web page means i am not able to ping the address.I am getting the message "The connection has timed out".

Is this both USBCDC and http code wont work together?
should i disable any interrupt routine in the USB or http code?

please help me to solve this problem?

with regrads,
Murthy.R

    I use LPC2378 in MCB2300 and I test usbcdc demo with VirtualCOM function and it works well. But when I change the bulk endpoint from EP2 to EP5, this demo works failed. In LPC2378 EP2 and EP5 are for bulk data transfer.

    There are three parts I modify for bulk EP5:
    (1) In usbdesc.c :
    /* Endpoint, EP5 Bulk Out */ USB_ENDPOINT_DESC_SIZE, /* bLength */ USB_ENDPOINT_DESCRIPTOR_TYPE, /* bDescriptorType */ USB_ENDPOINT_OUT(5), /* bEndpointAddress */ USB_ENDPOINT_TYPE_BULK, /* bmAttributes */ WBVAL(USB_CDC_BUFSIZE), /* wMaxPacketSize */ 0x00, /* bInterval: ignore for Bulk transfer */
    /* Endpoint, EP5 Bulk In */ USB_ENDPOINT_DESC_SIZE, /* bLength */ USB_ENDPOINT_DESCRIPTOR_TYPE, /* bDescriptorType */ USB_ENDPOINT_IN(5), /* bEndpointAddress */ USB_ENDPOINT_TYPE_BULK, /* bmAttributes */ WBVAL(USB_CDC_BUFSIZE), /* wMaxPacketSize */ 0x00, /* bInterval: ignore for Bulk transfer */

    (2) In cdcuser.h :
    #define CDC_DEP_IN 0x85
    #define CDC_DEP_OUT 0x05

    (3) In cdcuser.c :
    void USB_EndPoint5 (DWORD event) { switch (event) { case USB_EVT_OUT: CDC_BulkOut (); /* data received from Host */ break; case USB_EVT_IN: CDC_BulkIn (); /* data expected from Host */ break; }
    }

    Does anybody know why. Thank you
