    Hi,

You need take care the following things.

1. Endpoint Descriptor (in Configuration Descriptor)
   Define your endpoint at Configuration Descriptor as IN or OUT.
   Also make sure the bNumEndpoints is correct in the Interface Descriptor.

2. HID Report Descriptor
   You need define Input or Output Report in the HID Report Descriptor
   depend on the direction of your data (IN or OUT).

3. If the enumeration is find, you can use ReadFile/WriteFile to send/receive
   data for the IN/OUT interrut endpoint.

Hope the information is useful to you.

Sincerely,

WT
