isp1301 ?? there's a driver for that on drivers/usb/otg/isp1301_omap.c

enable that and check if it works. You should add something like the 
following to your board file:

diff --git a/arch/arm/mach-omap2/board-2430sdp.c b/arch/arm/mach-omap2/board-2430sdp.c
index 01d113f..910234d 100644

I didn't even compile tested... you will probably need the schematics to 
figure out to which i2c bus isp1301 is connected.
