Overriding Baud Rate : 9600
Using Port : usb Using Programmer : stk500v2avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104)
Board "Arduino nano".Yas ~/ARDUINO/arduino-1.8.9/hardware/arduino/avr/boards.txt modifiednano.menu.cpu.atmega328.upload.speed=9600
Why did you modify boards.txt?
Just tried to upgrade to 1.8.9 from 1.8.6. All my coded programs were written in 1.8.6. None (3) of my Nano'swill upload anymore, all I get is error messages. Unfortunately as the upgrade message suggested I uninstalled1.8.6 so I can't go back. Checked "tools" and all parameters are correct. Any help appreciated. Error messageis come here and look for suggestions. Thanks
anybody know what the reason why USBdetach() still empty in USBCore.cpp in 1.8.9 ?
