![]() I also have the 1.8.13 version of the Arduino IDE. Hence, I think my code (which uses timers) caused the Leonardo to crash and unable to be recognised by Windows 10. Okay, so I got a genuine Arduino UNO R3 here. I ended up buying a new board, and it worked initially, but after downloading my code to the board, it also ended in the same fate. I had used the advice from other forums of trying different USB ports, different USB cables, rebooting, reinstalling, that all failed. (This process worked on my 2 boards that had the exact same issue!) I tried various orders, but the order of steps above is the one that worked. The Arduino will flash various LEDs, and then the simple Blink sketch will load.Įventually I got it to work after numerous tries. The Windows 10 computer will make the sound about the USB port being disconnected, and then reconnected.Quickly double press the reset button on the Leonardo.(even though the board is not recognised in the IDE and the port is not found in Tools > Ports) Press Control-U on the keyboard to start the upload.I also struggled with this issue and I was able to it by using the Windows 10 Arduino IDE editor (not the web create), load one of the Basic sketches such as Blink, compile the sketch for my board Leonardo, plugging in the Arduino Leonardo into the USB port, which displayed the error message "usb device not recognized", and then Windows at least says they are when I attempt an update. I've tried to make sure all other USB related drivers are updated. I have disabled Driver Signature Verification already. However, going to Driver Details in Device Manager says: No driver files are required or have been loaded for this device. (Code 43)Ī request for the USB device descriptor failed.Īttempting to update the driver by pointing it directly to the proper directory gives a message that it already has the most up to date driver. It showed up as a unknown device and when i try to point to the driver it starts to install but says a driver could not be found. Right clicking and going to properties for the Unknown Device, reveals a status of: Windows has stopped this device because it has reported problems. (By the way, when I plug in the Arduino, I get a notfication that says the recently plugged in device has malfunctioned and Windows does not recognize it.) ![]() This is the Arduino, as when I unplug the Uno, this device disappears from the USB controllers section. Line in the Universal Serial Bus controllers section. Then it switches to an unknown device under usb controllers. I plug it in and for about ten seconds it recognizes the device as an Arduino Leonardo under 'Other divices'. "Unknown USB Device (Device Descriptor Request Failed)" I just purchased a Leonardo and Im having issues with it on 7. There is no Ports or Other Devices section. inf file is sitting in Arduino/drivers directory.Įxpected behavior is to plug in Arduino via USB, go to Device Manager, and find Arduino in Ports section or possibly Other Devices section. Have installed arduino software and drivers via official executable on Arduino website. I'm running Windows 10 Home on a 64-bit Dell Inspiron laptop. ![]() I have an Arduino Uno that will not - no matter what I've tried - get recognized by my computer.
