Try changing the following line:

USBH_MIDI/usbh_midi.cpp

Line 299 in bd8f4b5

if( pid == 0x20 || pid == 0x36 || pid == 0x51 || pid == 0x69 ) {

to

if( pid == 0x0e || pid == 0x20 || pid == 0x36 || pid == 0x51 || pid == 0x69 ) {

Yes I did and it still doesn't work. I tried changing the cable and it didn't work, I thought my usb host shield might be failing but when I connect it with a mouse or keyboard they work without problems. I changed the version of the Arduino IDE and it didn't work. I even tried on different computers one with Windows and another with Linux and it didn't work on any of them. I made a simple program to show you what I get in the Serial Monitor of the Arduino IDE. The output is the following:
USB Host Shield initialized
No MIDI device detected

The Program here:
#include <usbh_midi.h>
#include <usbhub.h>

// Initialization of USB Host and MIDI
USB Usb;
USBH_MIDI Midi(&Usb);

void setup() {
Serial.begin(9600);

// Initialize USB
if (Usb.Init() == -1) {
Serial.println("Error initializing USB Host Shield");
while (1); // Halt if it fails
}
Serial.println("USB Host Shield initialized");

// Wait a few milliseconds to ensure connection
delay(2000);

// Check if the MIDI device is connected
if (Midi) {
Serial.println("MIDI device detected.");
} else {
Serial.println("No MIDI device detected.");
}
}

void loop() {
Usb.Task(); // Update USB Host Shield
}

My Launchpad mini is also unstable, but it can sometimes be recognized when using a USB HUB.
