Apologies in advance for posting what I’m sure is a daily occurrence on here. However I’m on day 3 and I’ve exhausted every thread, blog and troubleshooting guide I could find. I’ve attached my verbose log during compile and upload for reference. I have an Arduino Uno R3 with a ATMEGA328P chip. I’ve tried to upload on three different computers now with no luck. I tried a windows 8 with the signature enforcement disabled, a Windows 7 and a Mac OsX, as well as a windows 7 on bootcamp on a Mac (same computer). I’ve installed the driver as well as manually ensuring it was installed using the hardware manager, I’ve confirmed that the Uno is being registered on a com channel and that the IDE is using the correct COM channel, has the correct board selected and have tried doing this in AVRISP, AVRISP MkII and Arduino ISP.
I’ve tried hitting the reset button before hitting upload, after, counting at various intervals between 1 and 10 seconds before and after upload, holding reset, unplugging and replugging the cable in during upload. I’m honestly unsure of what else to try. I’m reasonably certain the chip is working because when I hit reset the light does turn on and then blink after. I see the RX light blinking when upload is active but I get the exact same error messages on every set up, I’ve even tried using different USB cords.
It won’t let me burn the bootloader again either, it keeps giving me a device “USB” not recognized error. I know it’s not the program because I’ve checked it character for character against the examples (blinking LED) and I program in C for a living. I’m just not sure what else to check at this point.
