New kernel 3.11 and the V Synth GT miraculously appeared.
Great Daniel!!!
Both functions of USB / MIDI and USB drive work perfectly.
Problem solved.
In standard repository for OpenSUSE the update is not present, but I found it in the user repository
http://download.opensuse.org/repositories/home:/pontostroy:/drm-next/openSUSE_Factory/
I'm happy!!
Thanks

Just try a recent 3.11 rc kernel and report if that helps. If your distribution does not provide such a kernel image, you have to build it from the git sources.
