+ *
+ *  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.
