- *  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.
