 35	  If you say yes here you get support for the Philips ISP1301
 36	  USB-On-The-Go transceiver working with the OMAP OTG controller.
 37	  The ISP1301 is a full speed USB  transceiver which is used in
 38	  products including H2, H3, and H4 development boards for Texas
 39	  Instruments OMAP processors.
