enabling hardware synths vy disabling serial ports

[John G Heim]

Has anyone got their hardware synth to work by disabling the serial
ports in grub as the debian wiki suggests? It says to add a line to
/etc/default/grub, update the grub configuration, reboot, and you should
be able to load the driver for your synth. But it doesn't work for me
with my litetalk. It works exactly the same as always.
