Yes, they are both used in same time. As if you plugged in two different USB devices.
Go to device manager, and see if there is problem with driver (if you are using Windows OS).
Also, how do you upload sketch to bluepill?

Here is how my computer sees it.. The Midi Port is recognized.
I uploaded the sketch using the IDE itself via an FTDI adapter.
Thanks

Uf, windows and drivers...
There is few thngs you can try:
- right click on icons with problems, choose "uninstall" and click "scan for hardware changes" icon.
- right-click, "update driver", "Browse my computer for drivers", select path "c:\Windows" (check "include subfolders") and hit "next"
- do the same for "...Documents\Arduino\hardware\Arduino_STM32\drivers\" path...
- click "View" in device manager, "show hidden devices". Uninstall everything that you are not using anymore (multiple "My Device" or "Maple" )
- check for Windows update to solve your problem

There is also one more thing to try:
Code: Select all
USBComposite.setManufacturerString(ManufacturerName);
USBComposite.setProductString(DeviceName);
USBComposite.setSerialString(DeviceSerial);
USBComposite.setProductId(0x0029); // or any other number than 0x0020
I wouldn't recommend it until you try other solutions. Ideally, it should be unique number per "device" you are programming. I think default number is 0x0020, but it might be in conflict as same number is used for multiple things (MIDI, USB serial, USB microphone, USB speaker, etc...)

Thank you. will try all. I normally change the ID but I didn't change yours, so it should be different anyway.
will report later.. Banging my head against the wall at the moment because of "Processing"

I looked into driver itself on my computer, and it is using "USB serial driver" (Usbser.sys) that comes with Windows 10. If i'm right, and you are using Windows 7 (aero theme in your screenshot), google said that Windows 7 don't come with that driver. It might be a reason why your midi device is recognized, but not USB virtual serial port.
If you have time to play around, maybe you should install maple bootloader (don't forget to install drivers from "...Documents\Arduino\hardware\Arduino_STM32\drivers\win\" ) and try again your sketch.

Thank you for your tips. That would explain it.. I am still using windows 7 as this machine has not enough power for win 10
So I guess that the maple driver will work with the sketch you posted? I think I have installed it anyway, but maybe I might have done it wrong

Documents\Arduino\hardware\Arduino_STM32\drivers\win\
And i don't have this folder in the documents folder.. Do I have to download some file and create the folders?
Thanks

i think win7 has the 'drivers', but that it may take 'installing' it to make it work. e.g. in device manager do that 'update driver' step.
normally, these 'drivers' are done thru an 'install' procedure.
https://github.com/rogerclarkmelbourne/ ... stallation
in particular, the 'install' procedure, link the usb pid/vid to the correct 'driver', this is especially in the 'earlier' windows releases i think.
maybe windows 10 is 'improved' such that it doesn't bother about vid/pid and simply decides on the correct 'driver' based on the usb device class.
that is the appropriate way to do it, earlier 'windows' is still stuck to vid/pid i'd think.
so try that 'install' procedure. e.g. that link above given.

Thank you. Will read it and try it. And will report the outcome.
