NAME

     ipheth -- USB Apple iPhone/iPad tethered Ethernet driver

SYNOPSIS

     To load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_ipheth_load="YES"

     Alternatively, to compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device uhci
	   device ohci
	   device usb
	   device ipheth

DESCRIPTION

     The ipheth driver provides support for network access through Apple iPhone and iPad devices, often referred to as USB tethering.

     ipheth should work with any Apple iPhone or iPad device.  In most cases this must be explicitly enabled on the device first.

     For more information on configuring this device, see ifconfig(8).	The device does not support different media types or options.

HARDWARE

     The following devices are supported by the ipheth driver:

     o	 Apple iPhone tethering (all models)
     o	 Apple iPad tethering (all models)

SEE ALSO

     arp(4), cdce(4), intro(4), netintro(4), urndis(4), usb(4), ifconfig(8), usbconfig(8)

HISTORY

     The ipheth device driver first appeared in FreeBSD 8.2.

AUTHORS

     The ipheth driver was written by Hans Petter Selasky <hselasky@FreeBSD.org>.

BUGS

     Some devices may need to be manually configured to use an alternative configuration with the usbconfig(8) utility.  A command similar to
	   usbconfig -u 1 -a 2 set_config 3
     may be required if the device is not recognised automatically by ipheth after it is connected.

NAME

     cdce -- USB Communication Device Class Ethernet driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device uhci
	   device ohci
	   device usb
	   device cdce

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_cdce_load="YES"

DESCRIPTION

     The cdce driver provides support for USB Host-to-Host (aka USB-to-USB) and USB-to-Ethernet bridges based on the USB Communication Device
     Class (CDC) and Ethernet subclass.

     The USB bridge appears as a regular network interface on both sides, transporting Ethernet frames.

     For more information on configuring this device, see ifconfig(8).

     USB 1.x bridges support speeds of up to 12Mbps, and USB 2.0 speeds of up to 480Mbps.

     Packets are received and transmitted over separate USB bulk transfer endpoints.

     The cdce driver does not support different media types or options.

HARDWARE

     The following devices are supported by the cdce driver:

     o	 Prolific PL-2501 Host-to-Host Bridge Controller
     o	 Sharp Zaurus PDA
     o	 Terayon TJ-715 DOCSIS Cable Modem

DIAGNOSTICS

     cdce%d: no union descriptor  The driver could not fetch an interface descriptor from the USB device.  For a manually added USB vendor/prod-
     uct, the CDCE_NO_UNION flag can be tried to work around the missing descriptor.

     cdce%d: no data interface
     cdce%d: could not read endpoint descriptor
     cdce%d: unexpected endpoint
     cdce%d: could not find data bulk in/out  For a manually added USB vendor/product, these errors indicate that the bridge is not compatible
     with the driver.

     cdce%d: watchdog timeout  A packet was queued for transmission and a transmit command was issued, however the device failed to acknowledge
     the transmission before a timeout expired.

     cdce%d: no memory for rx list -- packet dropped!  Memory allocation through MGETHDR or MCLGET failed, the system is running low on mbufs.

     cdce%d: abort/close rx/tx pipe failed
     cdce%d: rx/tx list init failed
     cdce%d: open rx/tx pipe failed
     cdce%d: usb error on rx/tx

HISTORY

     The cdce device driver first appeared in OpenBSD 3.6, NetBSD 3.0 and FreeBSD 6.0.

AUTHORS

     The cdce driver was written by Craig Boston <craig@tobuj.gank.org> based on the aue(4) driver written by Bill Paul <wpaul@windriver.com> and
     ported to OpenBSD by Daniel Hartmeier <dhartmei@openbsd.org>.

CAVEATS

     Many USB devices notoriously fail to report their class and interfaces correctly.	Undetected products might work flawlessly when their ven-
     dor and product IDs are added to the driver manually.
