Thanks for your reply Rushang.Karia. I'm using the the micro-USB-A Slot titled "USB HOST" for my active Hub connected with the Display.
I updated the title of my thread, because it seems to be a more special problem.
I'm now using a second Galileo1 to verify my problem and its indeed the same.
Because the display works with win8 and ubuntu it must be a problem with the yocto.
Is there somehow the possibility to manually configure the usb device recognition in yocto without recompiling yocto myself?
Update:
When i Plugin the Odroid Show Display on my ubuntu $dmesg gives me this:
[ 6577.596398] usb 1-2: new full-speed USB device number 3 using ohci-pci

So i need to get the cp210x converter to the galileo. Is this somehow possible to copy to the galileo linux without recompiling yocto, so that i still can use the Arduino Ide 1.5.3?
