If it is, try building a new kernel with it turned off. Felipe: Is the usb_enumerate_device_otg() routine really correct? It looks like it will try to enable HNP whenever CONFIG_USB_OTG is set, even if the root hub isn't OTG-capable. The routine does this: /* enable HNP before suspend, it's simpler */ if (port1 == bus->otg_port) bus->b_hnp_enable = 1; err = usb_control_msg(udev, usb_sndctrlpipe(udev, 0), USB_REQ_SET_FEATURE, 0, bus->b_hnp_enable ? USB_DEVICE_B_HNP_ENABLE : USB_DEVICE_A_ALT_HNP_SUPPORT, 0, NULL, 0, USB_CTRL_SET_TIMEOUT); if (err < 0) { /* OTG MESSAGE: report errors here, * customize to match your product. */ dev_info(&udev->dev, "can't set HNP mode: %d\n", err); bus->b_hnp_enable = 0; } Maybe the usb_control_msg and the error check should be inside the first "if" statement?
