HI,
i bought a diamex All-AVR programmer flashed the latest firmware (V1.6) and connected it to an Arduino Uno (Rev 3). The Arduino is powered via the programmer and LED 13 of the Arduino is flashing which shows that the pre installed program and therefore the Atmega is working fine. I installed "AVRJungoUSB" and tried to upload a program with "AVRISP mkII" choosen as programmer and via "Upload with programmer". You can see the result in picture 1. Then I installed "libusb" (whereon the device driver entry, as can be seen in pic2, got an exclamation mark) and tried to upload again and the result can be seen in picture 2. I might add that I am working under a virtual Windows XP (on top of win7 64bit) and that I wasn't able to flash the programmer's bios from this virtual Windows, but only from win7! So could it be a problem of the virtual environment? I don't have problems uploading programs the usual way via direct usb connection of the Arduino!
Thanks for the answers in advance! I am working with ARDUINO IDE V1.0.1.
...seems I installed something wrong! Now after another try to install libusb (the "libusb" driver that came with the Arduinio IDE) the upload works fine (and very fast)!
