This provides a library which is used for packet I/O by USB DSL
modems, such as the SpeedTouch driver below.
Say Y here if you want to connect a USB Digital Subscriber Line (DSL)
modem to your computer's USB port. You will then need to choose your
modem from the list below.
To compile this driver as a module, choose M here: the
module will be called usb_atm.
module will be called usbatm.

Say Y here if you have an SpeedTouch USB or SpeedTouch 330
modem. In order to use your modem you will need to install the
two parts of the firmware, extracted by the user space tools; see
<http://www.linux-usb.org/SpeedTouch/> for details.
To compile this driver as a module, choose M here: the
module will be called speedtch.

help
Say Y here if you have an ADSL USB modem based on the Conexant
AccessRunner chipset. In order to use your modem you will need to
install the firmware, extracted by the user space tools; see
<http://accessrunner.sourceforge.net/> for details.
To compile this driver as a module, choose M here: the
module will be called cxacru.
config USB_XUSBATM
tristate "Other USB DSL modem support"
depends on USB_ATM
help
Say Y here if you have a DSL USB modem not explicitly supported by
another USB DSL drivers. In order to use your modem you will need to
pass the vendor ID, product ID, and endpoint numbers for transmission
and reception as module parameters. You may need to initialize the
the modem using a user space utility (a firmware loader for example).
To compile this driver as a module, choose M here: the
module will be called xusbatm.
