How to fix ESP32 S3 USB OTG HOST MIDI CHECK_SHORT_C

[serifpersia]

Built midi project with your library but seems like real midi devices(self powered) don't work on ESP32 S3 and probably on S2 as well?
Here is output from serial monitor
E (1604) HUB: Configuration descriptor larger than control transfer max length
E (1605) HUB: Stage failed: CHECK_SHORT_CONFIG_DESC

This is with normal Yamaha piano has dc power and usb midi port.

I have 0 issues with phone as midi or Arduino Leonardo as midi device both work fine maybe the descriptor is small enough so esp can enumerate the device without issues?

I'm using Arduino IDE 1.8 and latest esp32 arduino core

Any hints on how to fix this so any midi device will work(ofc if its standard usb midi device works without drivers)

Here is difference between working midi device and non working one(the error i mentioned above)

Configuration Descriptor (Working Device):
wTotalLength: 0x00AF (175 bytes)
bNumInterfaces: 0x04 (4 Interfaces)
bmAttributes: 0xA0 (Self-Powered, Remote Wakeup)
MaxPower: 0xFA (500 mA)

Configuration Descriptor (Problematic Device):
wTotalLength: 0x012F (303 bytes)
bNumInterfaces: 0x04 (4 Interfaces)
bmAttributes: 0xC0 (Self-Powered)
MaxPower: 0x01 (2 mA)


here is full configuration_descriptors for both working one and non working one
