Hmm. Seems I tried wrong device. But no vibrations with the right device, either: root@duo:/sys/class/leds/0003:054C:03D5.0002:global# echo 4 | fftest /dev/input/event8 Force feedback test program.

Not advertising both heavy and light motor. If I do this, I can control vibrations using the "red" led. Value of 70 is lowest that produces anything...
