Hello,
I'm trying to follow the instructions on using an Arduino Uno to burn my own ATMEGA328P-PU chip. It's blank.
After uploading the ISP sketch, I select the board as "Uno", and then select "Burn Bootloader". I get this error:
did not find any USB device "usb"
I think I have the wiring correct, according to http://arduino.cc/en/Tutorial/ArduinoISP. What else might be going on here? The screen shots I've seen of the Arduino.exe had other menu options under "Burn Bootloader", but on my copy, which is only a couple months old, there isn't any other options.
retrolefty:
Did you select programmer type to arduinoISP as the programmer type before you hit burn bootloader?
That's it. Thanks. I'm looking over the instructiosn and I don't see where it said to select the programmer type. I've never looked at the menu option before I don't think. Somehow it was the correct option when I'm downloading sketches to my Uno.

Two diffferent animals at work there. When you do a normal upload of a sketch to your attached Uno board, you are not using any programmer, you are rather required to select the proper com port for your arduino board attached to the PC usb port.
When you are using a ISP hardware programmer your target arduino board is not directly connected to the PC's usb connector, rather it is connected with wires or cables to a programmer (which can be a another Uno board running the arduinoISP sketch) and in that case there are only two methods to use the IDE, either burn bootloader or upload sketch using programmer.
So bottom line, when you are using normal uploading of sketches you have to select the proper com port, but do not have to select (or if you already did, it isn't used) a programmer type. When you are using a programmer you have to select the proper programmer type, but not required (or if you already did, it isn't used) to select a com port.
FYI, if you want to post the compile errors click File\Preferences in the IDE, check VERBOSE OUTPUT then compile . When you get the errors place your mouse cursor over the red compile error messages and hold the CNRL key down while pressing the "A" key.
The comiler output window should be highlighted. Press CNTRL-C the same way. Open NOTEPAD and place the mouse cursor in the NOTEPAD window and press CNTRL-V the same way. Save the file with a filename of your choosing and attach that to your post using the "Additional Options" button\Select file.
