I had this problem just yesterday when attempting to dump my presets trough FactorLib. Then I realized the TF has to be on MIDI mode, selecting DUMP -> PRESETS. When you do that, the TF says SENDING. At that moment (via usb) my FactorLib received my presets (using the OPEN FROM MIDI option).
I am not midi literate, but I guess the FactorLib does not work by just pluggin the cable to the TF, you must also indicate what you want to do.
