So clear when you point it out.

Sorry, I think we phrased this badly. We only get these issues when using mainline U-Boot and not a) the manufacturer default bootloader or b) the Pepe2K mod - both of which work perfectly with our test images. In each case we’re using the same OpenWrt OS images we’ve built ourselves between the tests with these different botloaders. I guess the deeper understanding we’re trying to get to is the proper relationship between bootloader and Linux: - Why would the very same OpenWrt image be able to find and use the USB hub or make use of GPIO 2 using these other two U-Boot variants but not mainline? - Does this point to us not performing important set-up steps in U-Boot or does our problem lie in our OpenWrt setup? (If the latter, why do these other U-Boots work properly?) - Are we stumbling into a common beginners’ problem?
