Hi, I was not aware of this. Sorry! I'll pull and rebuild. Thanks. I don't think the problem is related to the driver though because it never used to do that on any other kernels I've used. I've had it not detect the synth on the serial port but forcing it to ttyS0 solved that problem. Kirk Reiser wrote: > Hello Tony: I recommend you do a git pull.
