Hi,
I have just compiled the linux omap2 git kernel with MUSB in the OTG mode. It booted up the board without problem. But it does not detect any USB device (mouse, keyboard, card reader, usb key etc.) connected directly to the USB port or via un D-link HUB USB.
Here is the dmesg showing that the usb modules are correctly loaded:

Anyone got usb otg working correctly (with usb hub or not) ? Any idea please ?
Thanks.
