- OZWPAN USB Host Controller Driver
- ---------------------------------
- This driver is a USB HCD driver that does not have an associated a physical
- device but instead uses Wi-Fi to communicate with the wireless peripheral.
- The USB requests are converted into a layer 2 network protocol and transmitted
- on the network using an ethertype (0x892e) regestered to Ozmo Device Inc.
- This driver is compatible with existing wireless devices that use Ozmo Devices
- technology.
- To operate the driver must be bound to a suitable network interface. This can
- be done when the module is loaded (specifying the name of the network interface
- as a parameter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after
- loading using an ioctl call. See the ozappif.h file and the ioctls
- OZ_IOCTL_ADD_BINDING and OZ_IOCTL_REMOVE_BINDING.
- The devices connect to the host use Wi-Fi Direct so a network card that supports
- Wi-Fi direct is required. A recent version (0.8.x or later) version of the
- wpa_supplicant can be used to setup the network interface to create a persistent
- autonomous group (for older pre-WFD peripherals) or put in a listen state to
- allow group negotiation to occur for more recent devices that support WFD.
- The protocol used over the network does not directly mimic the USB bus
- transactions as this would be rather busy and inefficient. Instead the chapter 9
- requests are converted into a request/response pair of messages. (See
- ozprotocol.h for data structures used in the protocol).
