I know that there is plenty posts with this subject but non of them helped me! I tried a lot, trust me...
I have a brand new Arduino nano (Original one, not a Chinese) and it isnt recognized by the Arduino IDE software, but when Im trying the Arduino Create online web editor , it is recognized!
So why with the IDE software (not online) not recognizing it and with Arduino Create it is ?
I saw in the "Device manager" that this USB port (COM7) is written as "USB Serial Port (COM7)", and although this, in Arduino Create it succeeded to recognize the Arduino Nano.
I need to use the IDE software and not the Arduino Create because in Arduino IDE I have the option to change the processor, and I need to change it to the old bootloader... In Arduino Create, I didn`t find any option to change the processor.
I have another thing to mention which is important... I have also Arduino Uno (Original) and it works perfect! it`s recognized both in IDE software and Arduino Create.

I`ve noticed also that in the device manager the port has been configured as 9600 baud rate, while arduino IDE tries to upload sketeches with baud rate of 57600.
I changed it in the device manager to baud rate of 57600 and the problem still remains...
If it’s worked with the on line editor , with the same lead, the board will be ok .
Turn computer off and then on, go straight to the IDE ( not the online one) , go to tools , ports, and select the correct port ( which is not com1).
Again in tools select nano and try and upload blink. ( you can also try nano old bootloader )
Good luck and report back .
