That does not look too bad; there is a problem with one device and the
ehci_hcd driver, but that seems to be solved by switching to uhci_hcd.
The first thing we need to know is if the device node(s) for the USB
stick are created reliably. When you have a "first boot" and the icon
does not show up, please run
ls -l /dev/disk/by-path/ | grep usb
and post the output here (or let us know if there is no output).
