+ The U132 adapter is a USB to CardBus adapter specifically designed
+ for PC cards that contain an OHCI host controller. Typical PC cards
+ are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
+ adapter will *NOT* work with PC cards that do not contain an OHCI
+ controller.
+
+ For those PC cards that contain multiple OHCI controllers only the
+ first one is used.
+
+ The driver consists of two modules, the "ftdi-elan" module is a
+ USB client driver that interfaces to the FTDI chip within ELAN's
+ USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
+ controller driver that talks to the OHCI controller within the
+ CardBus cards that are inserted in the U132 adapter.
+
+ This driver has been tested with a CardBus OHCI USB adapter, and
+ worked with a USB PEN Drive inserted into the first USB port of
+ the PCCARD. A rather pointless thing to do, but useful for testing.
+
