EllipseD not working with other USB devices

[rmarcuzzi]

I'm trying to use the Ellipse D sensor using the USB cable connected to a USB hub and I'm getting SBG_TIME_OUT error, meaning that I can't connect to it. If I connect the device directly to the USB port of the computer it works perfectly, I can run the default example. However, when I connect it to the USB hub and try to run the example, it doesn't work. I see the same behaviour when connecting another USB GPS, I get also SBG_TIME_OUT. I've tried changing the baudrate from 115200 to 230400 and I see the same behaviour.
