CONFIG_USB_ACM
This driver supports USB modems and ISDN adapters which support the
Communication Device Class Abstract Control Model interface.
Please read <file:Documentation/usb/acm.txt> for details.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called acm.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_AUDIO
Say Y here if you want to connect USB audio equipment such as
speakers to your computer's USB port.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called audio.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_BLUETOOTH_TTY
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.
If in doubt, say N here.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called bluetty.o. If you want to compile it as
a module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_PRINTER
Say Y here if you want to connect a USB printer to your computer's
USB port.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called printer.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.

If you don't know what the SilverLink cable is or what a Texas
Instruments graphing calculator is, then you probably don't need this
driver.
If unsure, say N.
CONFIG_USB_USS720
This driver is for USB parallel port adapters that use the Lucent
Technologies USS-720 chip. These cables are plugged into your USB
port and provide USB compatibility to peripherals designed with
parallel port interfaces.
The chip has two modes: automatic mode and manual mode. In automatic
mode, it looks to the computer like a standard USB printer. Only
printers may be connected to the USS-720 in this mode. The generic
USB printer driver ("USB Printer support", above) may be used in
that mode, and you can say N here if you want to use the chip only
in this mode.
Manual mode is not limited to printers, any parallel port
device should work. This driver utilizes manual mode.
Note however that some operations are three orders of magnitude
slower than on a PCI/ISA Parallel Port, so timing critical
applications might not work.
Say Y here if you own an USS-720 USB->Parport cable and intend to
connect anything other than a printer to it.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called uss720.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.

device based on the EL1210A chip. Supported devices are:
Belkin F5U011
Belkin F5U111
CATC NetMate
CATC NetMate II
smartBridges smartNIC
This driver makes the adapter appear as a normal Ethernet interface,
typically on eth0, if it is the only ethernet device, or perhaps on
eth1, if you have a PCI or ISA ethernet card installed.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called catc.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_CDCETHER
This driver supports devices conforming to the Communication Device
Class Ethernet Control Model. This is used in some cable modems.
For more details on the specification, get the Communication Device
Class specification from <http://www.usb.org/>.
This driver should work with the following devices:
* Ericsson PipeRider (all variants)
* Motorola (DM100 and SB4100)
* Broadcom Cable Modem (reference design)
* Toshiba PCX1100U and possibly other cable modems
The device creates a network device (ethX, where X depends on what
other networking devices you have in use), as for a normal PCI
or ISA based ethernet network card.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called cdc-ether.o. If you want to compile it
as a module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_KAWETH
Say Y here if you want to use one of the following 10Mbps only
USB Ethernet adapters based on the KLSI KL5KUSB101B chipset:
3Com 3C19250
ADS USB-10BT
ATEN USB Ethernet
ASANTE USB To Ethernet Adapter
AOX Endpoints USB Ethernet
Correga K.K.
D-Link DSB-650C and DU-E10
Entrega / Portgear E45
I-O DATA USB-ET/T
Jaton USB Ethernet Device Adapter
Kingston Technology USB Ethernet Adapter
Linksys USB10T
Mobility USB-Ethernet Adapter
NetGear EA-101
Peracom Enet and Enet2
Portsmith Express Ethernet Adapter
Shark Pocket Adapter
SMC 2202USB
Sony Vaio port extender
This driver is likely to work with most 10Mbps only USB Ethernet
adapters, including some "no brand" devices. It does NOT work on
SmartBridges smartNIC or on Belkin F5U111 devices - you should use
the CATC NetMate driver for those. If you are not sure which one
you need, select both, and the correct one should be selected for
you.
This driver makes the adapter appear as a normal Ethernet interface,
typically on eth0, if it is the only ethernet device, or perhaps on
eth1, if you have a PCI or ISA ethernet card installed.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called kaweth.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_PEGASUS
Say Y here if you know you have Pegasus or Pegasus-II based adapter.
If in doubt then look at linux/drivers/usb/pegasus.h for the complete
list of supported devices.
If your particular adapter is not in the list and you are _sure_ it
is Pegasus or Pegasus II based then send me (petkan@users.sourceforge.net)
vendor and device IDs.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called pegasus.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_RTL8150
Say Y here if you have RTL8150 based usb-ethernet adapter.
Send me (petkan@users.sourceforge.net) any comments you may have.
You can also check for updates at http://pegasus2.sourceforge.net/
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called rtl8150.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
CONFIG_USB_USBNET
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
(GeneLink), NetChip and Prolific. Intelligent USB devices could also
use this approach to provide Internet access, using standard USB
cabling. You can find these chips also on some motherboards with
USB PC2PC support.
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.
This code is also available as a kernel module (code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called usbnet.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
