This section describes how user-mode applications and kernel-mode drivers operate HID collections.
In general, a user-mode application does the following: Calls device installation functions (SetupDiXxx functions) to find and identify a HID collection. Calls CreateFile to open a file on a HID collection. Calls HidD_Xxx HID support routines to obtain a HID collection's preparsed data and information about the HID collection. Uses IRP_MJ_READ requests to read input reports and IRP_MJ_WRITE requests to send output reports. Calls HidP_Xxx HID support routines to interpret HID reports. In general, a kernel-mode driver does the following: Finds and identifies a HID collection If the driver is a function or filter driver, it is already attached to the collection's device stack. However, if the driver is not attached to the collection's device stack, the driver can use Plug and Play notification. Uses an IRP_MJ_CREATE request to open the HID collection Uses IOCTL_HID_Xxx requests to obtain the HID collection's preparsed data and information about the HID collection Uses IRP_MJ_READ requests to read input reports and IRP_MJ_WRITE requests to send output reports Calls HidP_Xxx HID support routines to interpret HID reports For more information about operating a HID collection, see: Finding and Opening a HID Collection Enforcing a Secure Read For a HID Collection Obtaining Preparsed Data Obtaining Collection Information Handling HID Reports Freeing Resources |

现在有一个问题就是用Calls CreateFile to open a file on a HID collection.如果第二个参数设GENERIC_READ|GENERIC_WRITE,返回的句柄是无效的,如果第二个参数设为0,可以取得句柄,那第二个参数应该设置什么.
