1. Openpli doesn't have Device manager to make mount usb to /universe ... True
This is the reason i installed enigma2-plugin-systemplugins-mount manager 1.0-r5 mipsel.ipk and mounted the usb as universe.
The plugin can be used from the System menu and display the right mount for both devices (HDD and USB - universe).
2. The Symlink was only for trying to resolve because it doesn't work and because i have free time to play.
3. The line /dev/sda1 /universe auto defaults 0 0 not found in fstab and my pin is sdb1 so added the line according to.
sda1 is my hard disk mapped as Benny.

The problem is still the same. The universe is created in universe folder in flash. Of course i can jump (done before the same) but my memory is lowered by 4 MB after jumping to Avalon.

I was thinking the plugin will use the USB for storing universes but in my case it not.
