I have recently assembled a custom arduino zero using an Atmel SAM D21 microcontroller and have SUCCESSFULLY connected it to a friends computer and uploaded the “blink” program to make sure everything is good to go…but I cannot get it to interface with my laptop. I’m using Windows 7 (64 bit) with Arduino IDE version 1.8.2. I have also installed the most recent board driver for the Zero - Arduino SAMD Boards ARM Cortex-M0+. Whenever I plug the board into the USB port, it does not recognize the device. It doesn’t even show up under PORTS(COM&LPT): See Attachment “Port Issue”.
I have tried all of the following:
-Connecting to different USB ports (tried all of them)
-Making sure USB cable is fully secured to board and computer
-Tried older versions of the board driver
-Flashed the bootloader
-Updating Unknown Device Driver by telling it to look for device driver under
- This results in windows not being able to find the driver software: See Attachment “Driver
-Uninstalling and Reinstalling Arduino IDE and re-updating Arduino SAMD Boards ARM Cortex-M0+
The leds show that it has power when connected.
My friend is currently on vacation an unreachable to try and compare notes on why it works on his computer and not mine. I’m fairly new to all of this so it may be an obvious issue that I am unaware of, but I’ve searched the web for two days now with no luck.
Thanks for your help.
