IOCTL_GENERICUSBFN_DEACTIVATE_USB_BUS IOCTL

-description

This IOCTL code is nevtot supported.

This I/O control code (IOCTL) is sent by the user-mode service or application this request to notify GenericUSBFn.sys to deactivate the Universal Serial Bus (USB). When deactivated, the bus can no longer process bus events and handle traffic.

-ioctlparameters

-input-buffer

NULL.

-input-buffer-length

None.

-output-buffer

NULL.

-output-buffer-length

None.

-in-out-buffer

-inout-buffer-length

-status-block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.

-remarks

If this I/O control code (IOCTL) is being called synchronously, set the lpOverlapped parameter to NULL. If this IOCTL is called asynchronously, assign the lpOverlapped parameter to a pointer to an OVERLAPPED structure that contains a handle to an event object. The event objects signal when the operation is completed.

The return value is a BOOL value that indicates success or failure of the operation. TRUE indicates success, FALSE otherwise.
