Say Y here if you want to connect a USB Bluetooth device to your
computer's USB port. You will need the Bluetooth stack (available
at <http://developer.axis.com/software/index.shtml>) to fully use
the device.
This driver implements a tty inteface to a Bluetooth device. If
you want to use a socket based Bluetooth stack (like the BlueZ
stack), do not use this driver.
This driver implements a nonstandard tty interface to a Bluetooth
device that can be used only by specialized Bluetooth HCI software.
Say Y here if you want to use OpenBT Bluetooth stack (available
at <http://developer.axis.com/software/index.shtml>), or other TTY
based Bluetooth stacks, and want to connect a USB Bluetooth device
to your computer's USB port.
Do *not* enable this driver if you want to use generic Linux
Bluetooth support.
If in doubt, say N here.

This driver supports network links over USB with USB "Network"
or "data transfer" cables, often used to network laptops to PCs.
Such cables have chips from suppliers such as Belkin/eTEK, GeneSys

use this approach to provide Internet access, using standard USB
cabling. You can find these chips also on some motherboards with
USB PC2PC support.

support include such chips.
Intelligent USB devices, such as PDAs running Linux (like Yopy
and Zaurus, or iPaqs after upgrading to Linux) can use the same
approach to provide Internet access.
These links will have names like "usb0", "usb1", etc. They act
like two-node Ethernets, so you can use 802.1d Ethernet Bridging
(CONFIG_BRIDGE) to simplify your network routing.
