Hi there,

i connected my new Leonardo to my PC the first time yesterday. (Win 7 x64, IDE 1.0.1)
I had to install the driver manually using the device-manager.

All worked just fine for about 2 hours, but suddenly i couldn't upload sketches to my board anymore.

I took a look into the device manager, and the arduino were listed as "Unknown Device".

From then on, everytime i plug the board to my pc, the Arduino gets recognized as "Arduino Leonardo" for about 10 seconds, but then it switches to "Unknown Device".

I tired re-installing the drivers and such things, but i can't work with it either way.

Thanks for your help!

Anything on the board getting hot?

Anything connected to the board?

Have you tried a different USB cable?

Have you tried a different USB port on the computer?

Hi,
thanks for your fast response.

Anything on the board getting hot?

No.

Anything connected to the board?

Nothing.

Have you tried a different USB cable?

Only have one cable with this particular connector, so no.

Have you tried a different USB port on the computer?
Not working with usb-hub nor direct to the mainboard-plugs.

Any other ideas?

Have you tried jiggling the cable?

I had a similar issue (device disconnects from windows after about 12 seconds after I uploaded a sketch), BUT, my device disapears entirely, (bing-bong) I don't have an "Unknown device"...

Just in case it helps...

Hi,

I tried uploading the blink sketch while the arduino is connected for a few seconds.

I had to try it a few times, but now it's working again!

Thank you so much!
