Yes. That's normal.. once the ext2 and ext3 modules have been loaded into the kernel then there is no point in re-loading it.. qole does not do any checks against lsmod to check if they have already been added.. he just runs insmod.. so the terminal is saying it's already there.. nothing to do.

And the /media/usb will only be there if you are using a usb device in host mode.. so it's mounting an empty directory and failing.

Everything else is fine. You'll only see that hte first time you run it on a reboot.. subsequent runs will skip that part.
