ESP32S3 USB MIDI problem

[aberoev]

Hello

Thank you for the great library I have made a DAW controller using Arduino pro micro, love it!!

I am now trying to make ESP32S3 board work, but with no success. I installed espressifs arduino core v 3 like suggested in the documentation and chose ESP32S3_USB-OTG as board

This example sketch compiles (although incredibly slow, takes a couple of minutes!) and uploads, but the board does not show up as a USB MIDI device on my PC.

The board is a Lilygo T-QT Pro.

As for the very slow compiling issue, I have tried installing IDE 1 as suggested by some users with the same problem, but it is still very very slow on my windows machine. Makes trouble shooting this issue very time consuming :)))

Any hints? Thank you

chose ESP32S3_USB-OTG as board

Are you sure this is the correct board? The link you posted seems to recommend using the ESP32S3 Dev Module, which is also the one I used during testing. The ESP32S3_USB-OTG is quite a special board.

Did you select USB-OTG (TinyUSB) from the Tools > USB Mode menu?

Do you see any warnings during compilation?

although incredibly slow, takes a couple of minutes!

A cold build takes around 1 minute on my 2017 i7-7700HQ (running Ubuntu 22.04), and a re-build takes around 25 seconds. This is quite a bit slower than some of the 8-bit AVR Arduinos, but not too bad considering the difference in features between an ESP32 and an AVR.

Wait a minute,

The device is shown in device manager as "Universal serial bus device" - not under Sound, video etc. It does not show up in morningstar midimonitor or Cubase as a midi device. So close yet so far :)

I've never come across this issue before, and I don't use Windows that often, so I'm afraid I don't have any concrete suggestions. However, Microsoft does have some tools to inspect USB devices and their USB device descriptors etc.: https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/usbview

Thank you tttapa

I will post to this thread if I find a solution.

It seems the discover-able device presents itself as a USB JTAG debug unit

Under events, some interesting details appear:

Device not migrated information:

`Device USB\VID_303A&PID_1001&MI_02\7&3371e176&0&0002 was not migrated due to partial or ambiguous match.

Since you're mentioning JTAG: GPIO3 (a pin used in the RotaryEncoder example) determines the JTAG source of the ESP32S3. I don't know if this is relevant, but I thought I'd mention it just in case. https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-2_datasheet_en.pdf#page=15

Hello tttapa just an update on this issue. I've tried updating to Windows 11, but the problem didn't go away.

I just got a XIAO ESP32S3 module in the mail and immediately tried uploading a control surface sketch. It works beautifully on my PC. So apparently the Lilygo T-QT board just doesn't want to talk to my Windows computer with HID. Perhaps it is something with the arduino-esp32 core / tinyusb implementation for that specific board, I have no idea.

Both boards make a midi device appear on bespoke wife macbook, but only the Xiao board appears as a midi device on my Windows PC.

When looking at a "Device Monitoring Studio" I get a midi instance with the Xiao board

With the Lilygo board I get a USB bus device called TinyUSB Midi but it's not a midi instance.

So, not a solution, but some more info for anyone interested.

Hallo I think I have the same issue with a ESP32-S3-Devkit v1.0 (ESP32-S3-WROOM-1). I flashed some very basic code just to get the interface instantiated but no midi device available, just as "USB JTAG/serial debug unit". Didn t check with other OS apart from Windows 11.

So, if anyone arrived here with the same issue: I had the current esp32 core definition in Arduino IDE (v2), so I changed it to the dev version as per instructions, it seemed like the board definition updated correctly but then I decided to reboot Windows as the usual last remedy and effectively when I started the IDE the boards were updated and now the Midi device si showig up correctly.
