I also had issues with upload (Arduino IDE). It would take sometimes 5-6 consequent tries and still not uploading. Found the solution, which is weird - immediately after pressing upload, press "boot" and hold, the press "reset" and release it, then release "boot". Works almost 100% ...
Describe the bug If I connect my Arduino Nano Every for the first time to the PC via USB, the Serial Output in Serial-Studio is shown as unreadable gibberish. If I use another program ( CoolTermWin inmy case) to establish the Serial conn...
I think the Arduino Community Forum would be the place to seek assistance, but before posting a new question have a look at this Arduino Support document: If your board does not appear on a port in Arduino IDE. That seems to describe what you're encountering perfectly. View in context Sim...
In particular, if I plug a device in, use it from the command line (with avrdude), and then launch Arduino IDE, the device disappears from the bus in the manner described in this question. After the enumeration fails, if I try again I see this in the Console: error 21:01:34.461045+...

Do you mean that COM2 is already in use by some other device? If you absolutely must use COM2 then you can disable or uninstall that other device that is currently allocated to COM2, or change its number to some other COM number so that you can use COM2. The preferable option is to...
Maybe you can improve this utility adding a sort of identification based on PID&VID like this add-on for the Arduino IDE https://github.com/per1234/zzInoVIDPID Amr Bekhit 23 May 2019 Reply That’s a good idea – I’ll have a look at integrating something like that in. Xeon 23 May...
(!) Mount-USB project code for the Arduino Pro Micro board. I have incorporated a workaround for the Arduino USB-CDC bug, with no patching or other weirdness required. No special libraries either, so this one is really simple to set up and build, in a freshly installed Arduino IDE....
The preferable option is to change your code so that your device can be any COM number.If your device can only be installed as COM2 then you should contact the manufacturer for a new device. Current Windows systems can accommodate any COM number....
