+ *
+ * The vstusb module is a standard usb 'client' driver running on top of the
+ * standard usb host controller stack.
+ *
+ * In general, vstusb supports standard bulk usb pipes. It supports multiple
+ * devices and multiple pipes per device.
+ *
+ * The vstusb driver supports two interfaces:
+ * 1 - ioctl SEND_PIPE/RECV_PIPE - a general bulk write/read msg
+ * interface to any pipe with timeout support;
+ * 2 - standard read/write with ioctl config - offers standard read/write
+ * interface with ioctl configured pipes and timeouts.
+ *
+ * Both interfaces can be signal from other process and will abort its i/o
+ * operation.
+ *
+ * A timeout of 0 means NO timeout. The user can still terminate the read via
+ * signal.
+ *
+ * If using multiple threads with this driver, the user should ensure that
+ * any reads, writes, or ioctls are complete before closing the device.
+ * Changing read/write timeouts or pipes takes effect on next read/write.
+ *
