AVRDUDE Error uploading a sketch.

Hello,

I ran into a small issue while trying to use the 1.0 version of Arduino IDE I receive this message: avrdude: usbdev_open(): did not find any USB device "usb"

The catch is that if I use the 0.23 version of Arduino IDE, it uploads verry fine.

I tried to reinstall the arduino drivers, reinstall the application... but it did not solve the problem. Can someone help me with this issue? I use: Win 7 x64 Board: Arduino UNO

Thank you.

Are you Uploading or Uploading Using Programmer?
