Hi, I suggest that you remove the USB hub from the mix. Using the Airport Extreme 4th Generation and newer does work well with time Machine and external HDs connected via USB. Apple has not recommended this but it works flawlessly in numerous situations I have set up. There are some situations where certain drives with built-in sleep functionality do cause issues but, in most cases, this is not an issue.
