+	  The U132 adapter is a USB to CardBus adapter specifically designed

+
+	  For those PC cards that contain multiple OHCI controllers only the

+	  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.
