    Upload an sketch doesnt work.

    Hi,

    i have a problem with my teensy 3.2. Every thing worked great, but now nothing works anymore. When i want to upload a sketch in Arduino this comes in the console. "error sending reboot command (HID)
    Teensy did not respond to a USB-based request to enter program mode.
    Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.
    "

    But when i open the seriel Monitor it detects that the teensy is online. And the port name is : hid#vid_16c0&pid_0485 MIDI (Teensy 3.2).

    Can anyone help me?

    Do you mean "now it's working"?

    Is that Windows 7 or 10 or something else? Windows 7 has a lot of USB driver problems. Microsoft fixed so many bugs for Windows 10, but they never ported those fixes back to Windows 7. On Windows 7, the driver can get confused if you press the button on Teensy or unplug the cable while the serial monitor is open. The really confusing part is the problems happen later, the next time you use Teensy (or after rebooting your computer). It's definitely a driver bug in Windows. Microsoft fixed that and many other minor problems, but only in Windows 10.
