You are wrong ...
universe folder in correct place (root) ...
Why you make Symlink from media to root ?! this is wrong..

Just install plugin > then must to be mount your usb pin to /universe direct no need to create Symlink to media ...

Openpli doesn't have Device manager to make mount usb to /universe ...
So after install plugin on openpli open (fstab) file from /etc and put this line
Code:
/dev/sda1    /universe    auto   defaults    0  0

make sure your pin is (sda1)
then reboot box after reboot try plugin again and do jump ...
after jumping give this command in telnet and post here your result
Code:
cat /proc/mounts
