I use Teensy Loader 1.23, Arduino 1.0.6

When I choose the USB type: Serial + Keyboard + Mouse + Joystick, the serial is not working. After uploading a code with this USB type, the usbmodem does not appear in the Serial menu choices, nor in [serial] objet port choice in Max.

That said, Serial works fine with USB type: Serial.

For tests, I use only a basic code.

My main goal was to do my own composite USB type with Serial + Midi, and I can not make that to work either. I reckon it is the same problem.

usb_desc.h and usb_desc.h seam ok, so I am a bit stuck.

Any ideas of where I should look? What the problem could be?

Many thanks!
