I just don't like the idea of deliberately sending a NULL object to
a callback.
Ha ... I know what is causing the crash....its in usb_urb.c
int usb_urb_init(struct usb_data_stream *stream,
struct usb_data_stream_properties *props)
{
int ret;
if (stream == NULL || props == NULL)
return -EINVAL;
memcpy(&stream->props, props, sizeof(*props));
usb_clear_halt(stream->udev, usb_rcvbulkpipe(stream->udev,
stream->props.endpoint));
The usb_clear_halt with 0 endpoint.
It can tweaked by sending a valid endpoint.
