The primary console of beagle is the serial header.
A secondary console is to use the usbtty. The user can set this manually by doing
setenv stdout usbtty; setenv stdin usbtty; setenv stderr usbtty saveenv
usbtty will be usable by accessing the /dev/ttyACM0 on a linux host.

We can either define CONFIG_MUSB_UDC or CONFIG_MUSB_HCD (host support), so I think it's better to move host and device specific definitions within CONFIG_MUSB_UDC or CONFIG_MUSB_HCD.
#ifdef CONFIG_USB_OMAP3
#ifdef CONFIG_MUSB_HCD
<here define all host specific definitions> #endif
#ifdef CONFIG_MUSB_UDC
<here define all device specific definitions> #endif
#endif /* CONFIG_USB_OMAP3 */
This change would make it easier to test Host or device functionalities.

I am not adding host support. Tom
