Code:
insmod: can't insert '/mnt/onboard/.kobo/KoboLauncher/usbnet/arcotg_udc.ko': invalid module format
insmod: can't insert '/mnt/onboard/.kobo/KoboLauncher/usbnet/g_ether.ko': invalid module format
ifconfig: SIOCSIFADDR: No such device
About epub bug, I commented out "$root/KoboLauncher -qws" in KoboLauncher.sh and it works, so it's something related to the launcher itself. Sorry for the confusion.
PS: KoboLauncher.log.txt is growing a little...
