Hi David,

Thanks a lot for your reply !
I hv one more doubt. The endpoints details provided in USB serial
client driver has
BULK IN ,BULK OUT and INTERRUPT IN endpoints (written below) for both
high speed and full speed.
I am supporting only Interrupt In (EP2) and Interrupt out (EP4)
endpoints in my USB Fn driver.

Now what all i need to do to make it compatible with MS provided serial
client driver?
OR I must use BULK IN and BULK OUT endpoints only in my USB Fn driver?

static UFN_ENDPOINT g_HighSpeedEndpoints[] = {
{
sizeof(UFN_ENDPOINT),
{
sizeof(USB_ENDPOINT_DESCRIPTOR),// bLength
USB_ENDPOINT_DESCRIPTOR_TYPE, // bDescriptorType
BULK_IN_ENDPOINT_ADDRESS, // bEndpointAddress
(endpoint 1, in)
USB_ENDPOINT_TYPE_BULK, // bmAttributes
HIGH_SPEED_BULK_PACKET_SIZES, // wMaxPacketSize
0x00 // bInterval (interrupt
only)
},
NULL
},
{
sizeof(UFN_ENDPOINT),
{
sizeof(USB_ENDPOINT_DESCRIPTOR),// bLength
USB_ENDPOINT_DESCRIPTOR_TYPE, // bDescriptorType
BULK_OUT_ENDPOINT_ADDRESS, // bEndpointAddress
(endpoint 2, out)
USB_ENDPOINT_TYPE_BULK, // bmAttributes
HIGH_SPEED_BULK_PACKET_SIZES, // wMaxPacketSize
0x00 // bInterval (interrupt
only)
},
NULL
},
{
sizeof(UFN_ENDPOINT),
{
sizeof(USB_ENDPOINT_DESCRIPTOR),// bLength
USB_ENDPOINT_DESCRIPTOR_TYPE, // bDescriptorType
INTERRUPT_IN_ENDPOINT_ADDRESS, // bEndpointAddress
(endpoint 2, out)
USB_ENDPOINT_TYPE_INTERRUPT, // bmAttributes
MAX_INTERRUPT_ENDPOINT_PACKET_SIZE, // wMaxPacketSize
0xc // bInterval (interrupt
only)
        },
        NULL
    }
};

With Regards,
Ajay
