Hi All
Has anyone been successful at connecting devices with a powered usb hub? I am starting to think that the Galileo isn't auto sensing and needs a cross over cable as I can't seem to get the Galileo to recognize anything plugged into a powered USB hub that is connected to the usb host port. I want to try to hook up a USB camera and sound card, like I did with the Ardunio Yun and Raspberry Pi (see http://dev.mikamai.com/post/76945627390/you-cant-touch-this-an-evil-arduino-based-alarm)
I know the hub is good, as it works with the Yun and Pi. I know the cable connecting the USB host port to the hub is good, as the Galileo recognizes a USB hard drive when it is directly connected to the Galileo via the cable,(dmesg)

but if I unmount and unplug the drive, and connect the cable to the hub and the drive to the hub, the Galileo doesn't see it or any of the other devices (Webcam & sound card attached to the hub -nothing in dmesg or lsusb).

I am using the standard Yocto image from https://communities.intel.com/docs/DOC-22226 on a Generation 1 card and have updated the firmware.
Any assistance would be appreciated.
thanks
