+  Say Y here if you want to connect an Alcatel SpeedTouch USB modem to
+  your computer's USB port.
+
+  This driver provides an ATM interface that uses the modem to
+  transfer data.  You must enable (Y or M in config) ATM (under
+  Networking Options) to use this driver. Information on this API may
+  be found on the WWW at <http://linux-atm.sourceforge.net>.
+
+  This driver is a revised version (that doesn't look much like the
+  original) of Johan Verrept's 1.5 SpeedTouch Driver.
+  Among the improvements of this 2.x branch are:
+  - Much more stability (hopefully); no deadlocks on shutdown
+  - Tons of locking added: SMP should work (not tested, I don't have a
+    suitable machine)
+  - Unlimited number of devices without compile-time configuration
+  - Processing of received data in URB completion handler, by default,
+    or in separate thread if configured at compile time
+  - If using PPPoATM, pppd will notice disconnection (thus you can
+    disable LCP echos and set configure request to 100000000)
+  - Inside the kernel tree
+
+  To use the device you also need a user-mode daemon that downloads
+  the firmware and (re)initializes the modem. Currently the only
+  working one is a closed source one from Alcatel that you can get at
+  <http://www.alcateldsl.com/support.htm>.
+
+  However, there is a lot of hope, since Benoit Papillaut has written
+  an user-mode driver that contains a program that with some
+  modifications can be used to replace the closed source
+  daemon. Anyway, you will still need the Alcatel daemon package to
+  extract the modem firmware from it.
+
+  For more information, see Johan Verrept's webpages at
+  <http://linux-usb.sourceforge.net/SpeedTouch/>.
+
+  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 speedtouch.o. If you want to compile it as
+  a module, say M here and read <file:Documentation/modules.txt>.
