Hi,
I have used Arduino Mega, Uno and Nano's to date, and they all work just fine. No issues.
Now I am trying to get my first Leonardo to work, but with very limited joy.
I have searched the web and probably every Arduino forum discussion about Leonardo and Windows 7 (64 bit). Some people say that they have managed to get the problem fixed by replacing cables, installing updates, updating the driver manually, some others just seem to disappear (probably gave up on trying to make it work). I have tried every possibly fix I could get my hands on thus far - and nothing seem to work!
Here is my situation:
- None of the USB ports on my PC pick the Leonardo up correctly. It gets installed as a "USB Composite Device", but then with the error "This device cannot start. (Code 10)"
- If I look into the properties, then the HW ID's shows the PID and VID as:
- USB\VID_2341&PID_8036&REV_0100
- USB\VID_2341&PID_8036
and that corresponds to the Leonardo details in the ..\Arduino\Drivers\arduino.inf file.
I have also installed Arduino 1.0.1, 1.0.5 and even tried 1.5.7 to see if any of the older drivers or drivers associated with the BETA Arduino SW works. None did.
I even tried testing it on a different 64 bit Windows 7 machine (at work I have got a HP PC that also runs Windows 7, 64 bit) and the Leonardo also does not work on any of the USB ports.
Now here is the interesting part - I have installed an old USB port expander (PCI slot) in my PC. If I plug the Leonardo into any of those USB ports, it works!
Can anyone please give me some advice on what I can look for next? I am really out of ideas.
Thanks for your advise.
Jan
