	Have been using an FTDI USB-to-serial adapter to program my Arduio Micro Pro devices. Adapter appears as COM3 on my PC. All working beautifully UNTIL.... ....I plugged in an Arduino Uno, which has it's own on-board USB port. The computer detected it, loaded the driver and assigned it COM4. I was able to upload programs to the Uno just fine. BUT... ....I unplugged the Uno and plugged in the FTDI adapter to program some more Micro Pro devices. The adapter was recognised and assigned its usual COM3. However, it will no longer upload the program to the Arduino. The compilation works fine, it reports "Uploading" but nothing happens. No flickering LEDs on the FTDI adapter, and after a minute or so it reports an error (see attached). Left the adapter plugged in (and plugged in to the Arduino Micro Pro as well). Shut down Visual Studio. Opened the Arduino IDE. Adapter still visible to it as COM3. Opened the same source file, compiled it, and this time it uploaded straight away. To repeat: FTDI adapter was not unplugged and replugged. Thus some trouble with Visual Micro. I'm tempted to uninstall Arduino and Visual Micro, then reinstall them again, as I suspect it will fix it. However, is this a known problem with a known solution? Is there anything you'd like me to record for a bug report before I vape it?

	Visual micro sues windows/c# to check ports, Arduino uses java so that can be the only difference. Please switch on vMicro>Verbose then post what you see. This should show us ide version, hardware and show which command vm is attempting to use.

	Oh, what an idiot!! I left the board type set to Uno! I've just corrected it and now it uploads perfectly. I am so sorry for wasting your time. As this thread will be of no help to anyone, feel free to delete it if you wish! My apologies again.

	Well it's good to hear that Thanks for the update.

	Of course, you do realise that your next job is to make Visual Micro detect the board type automatically!

	Yes I have been thinking about that, or at least a warning if upload fails to say that the board looks like something else.

	Actually, in all seriousness that, at least, would be very useful. I'm sure I'm not the first person to be completely flummoxed by forgetting to set the board type correctly. A warning to "Check the board type is set correctly" when an upload has failed would be very helpful. I don't feel so bad about it now!
