I am not a USB specialist, but it seems like it is the first time ever that U-Boot meets a board where the core's USB port is mapped directly to a device without passing through a hub. Is this design compliant with the USB standards? Anyway, you seem to have nailed the (USB) root cause, so the course of action is obvious even if its compliance with standards is not: you need to make usb hub probing and configuration optional and enabled by default, and to disable this option for your custom board. > manukumar > signal-networks Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
