  • I have a similar issue. using Windows 7 32 bit, hardware manager , Leonardo appears installed correctly for about 5 seconds, after which it seems to disconnect and connect back as unknown usb device. I tried installing it according to the instructions on the website, no success. I then tried to use it in Ubuntu 32 bit: first arduino IDE recognizes it, then I upload a sketch successfully. After about 20 s it appears as if its disconnected. If I press reset on the leonardo or restart the IDE all is good for another 20 s.

    Any thoughts?

    PS: i tried 2 different USB cables, 2 different computers, 3 different USB ports, and all are the same.

No public wish lists :(
