I also tried a different PC with Windows 7 64bit on it, and instead of getting recognized as a Leonardo, this time it came straight to becoming a "Unknown device". Uploading a code results in the bar being filled up and "Uploading." message, while maybe after a few minutes a very long error pops up without anything specific since you can plug out the board and get the same error. In the IDE, the Pro Micro is detected as being on "COM1" no matter what COM port it really is, or is it even plugged it at all. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12. The Arduino Leonardo Microcontroller (With Headers) can be powered via the micro USB connection or with an external power supply. I tried installing the drivers as given by sparkfun over the "unknown device" and no luck by trying, I always get an error saying that Windows has already the best drivers for it already installed.Īnd later, I uninstalled the "uknown device" in hope that it will re-install itself upon pluggin it back it, and it actually disappeard totally and got repalced by "Unknown USB Device (Device Descriptor Request Failed)" under USB controllers in the Device manager.Īnd I'm stuck here. The Arduino Leonardo is a microcontroller board based on the ATmega32u4. Afterwards, my Arduino got detected as an unknown device where I can't use it anymore. 11k 9 9 gold badges 46 46 silver badges 87 87 bronze badges. So, after I firstly plugged it in, it was detected as a Leonardo, rather than a Pro Micro, afterwards I installed hte drivers as noted by Sparkfun, and added the board to the IDE. But could not find anything about that in the ATmega32u4 datasheet, or any other Arduino Micro related websites. So I've got myself a Arduino Pro Micro ATmega32U4 5V 16MHz and my PC (Win10 64bit) won't recognize it.
