Hi! I have a problem with my Arduino Leonardo. If i want to upload a sketch which is bigger than 12kBytes the RX led is always on and Windows says "USB device isn't recognized". When the sketch size is under 12kBytes, e.g. 11,5 kBytes the Arduino works very well without problems. The special Reset function (" hold the reset button while uploading ") doesn't work and the Arduino Software doesn't report any errors or warnings!
Is there anyone who has the same problem or can help me to deal with it?
I'm using Windows 7 64bit and the Arduino Software Version 1.0.3 The Maximum sketch size of the Leonardo is 28672 Bytes
Thanks in advance ...
