Thanks for the tip CrossRoads. The solution is actually really simple....

Reboot the PC (press F8) and select  'Disable Driver Signature Enforcement'. The driver will now be signed and working!

Needless to say it worked straight away with the Arduino IDE... I'm really surprised this solution is literally missing from the hundreds tutorials and videos... I had to look in the Windows 7 Developer forums for a fix to unsigned drivers..

I think you're on to my problem. I'm still getting the yellow exclamation point saying my driver is unsigned (although it also says it's working) but in this case i'm thinking AVRdude is not picking up the programmer. Are you using windows 7 by chance? It looks easy enough in XP or Vista as you pointed out but i'm finding lots of problems getting this to work on W7. I hope I don't have to partition an XP just to bootload a stinkin arduino!

Cheers!

I followed this tutorial to the 'T' and no luck for both the 0023 & 1.01 Arduino IDE's. Same exact error message. Does this have any dependence on the COM port? I get this feeling i'm missing something simple...

thanks for the help!

4  Using Arduino / Installation & Troubleshooting / Trouble Burning the Bootloader to Arduino Uno [SOLVED] on: November 14, 2012, 08:43:45 pm
Hey guys & gals,

I'm trying to burn the Arduino Bootloader to an Arduino Uno w/ the bootloader already on it (this is a process confirmation attempt before burning the bootloader to my own custom arduino board).

I've scoured the web and found some great tutorials that have led me no where; i feel i'm missing something simple here since I'm always getting the same message:

"avrdude: usbdev_open(): did not find any USB device "usb" "

Here's how i'm connected: USB-B from PC to AVRISP MKII, AVRISP MKII to Arduino Uno with ICSP standard connector, 5V barrel DC power source from the wall powering the Uno.

I go into the Arduino IDE (1.01) and select the Arduino Uno as the board and the AVRISP MKII as the programmer. Then I hit 'burn bootloader'. The above error message ensues.

I do not have avrstudio installed and I have the atmel (unsigned) driver isntalled. The AVRISP MKII pops up in my device manager with the yellow exclamation point as expected (so i've read).


What gives? I hope it's something simple!


Cheers,

Brian
