Cannot enumerate usb devices [XM]

I am trying to build a kernel from the omap git tree which is working
find so far (able to cross compile, boot, etc) but I cannot seem to
get the lan usb hub chip (LAN9514) powered (D14 LED doesn't come on)

configs that I changed:

CONFIG_TWL4030_USB=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_NET_SMSC95XX=y
(more but don't exactly remember)

In my boot message though I get this:

I'm guessing that last line give hint as to whats wrong.

I know my hardware works because the angstrom image boots up fine.

What am I missing here?

dunno, I tried linux omap git tree on beagle C3, usb hub seems to work
ok, config based on omap2plus_defconfig here http://pastebin.com/y3NFsq4u

Figured it out.

Apparently the omap git tree hasnt been keeping up to date with
patches for beagleboard or something

in file:

arch/arm/mach-omap2/board-omap3beagle.c

The direction should be 1, not 0. It is active HIGH

  /* TWL4030_GPIO_MAX + 0 == ledA, EHCI nEN_USB_PWR (out, active low)
*/
  gpio_request(gpio + TWL4030_GPIO_MAX, "nEN_USB_PWR");
  gpio_direction_output(gpio + TWL4030_GPIO_MAX, 1);

In the angstrom git tree they have a conditional detecting which board
it is and sets the direction accordingly

Ethernet and USB work now.

Will you be submitting a patch to linux-omap to fix? Sorry for being so slow in the submissions. Fortunately, Robert has been picking up several.

Yeah ill submit a patch to detect board version
