Hi! I have problems uploading my Arduino Leonardo, the message I'm getting is:
avrdude: ser_open(): can't set com-state for "\\.\COMXX"
avrdude: ser_send(): write error: sorry no info available
I'm under Windows 7, I am sure that the COM port is correct and everything used to work. I also tried to remove the device driver and reinstall it several times... but it's the same
The last important change I made, that might had affected it, was at the HID.cpp file in the hardware core. I added a new device other than the mouse and the keyboard, everything compiles fine. I know other people were able to make similar changes with no problems (http://blog.qwertymodo.com/2012/11/arduino-hid-gamepad-part-2.html
, I'm actually trying to implement a touchscreen not a gamepad). Yet it is the only thing that might have affected it.
Any idea on how I may get it back to work?
