Using a 3.6 board...
Be kind... I am very new at this...

Trying to transmit midi data (sysex specifically) out the 2nd USBHost port

I have data monitors on both the 1st (slave) and the 2nd host ports.

Midi out over the 1st port (slave) works perfectly.

Midi out over the Host port - "appears" to not transmit anything....

I have tried to simplify the code based on examples provided, however have been unsuccessful and thought I must be doing something wrong....
Any help or guidance would be greatly appreciated.

Code example ( is this correct ?)

#include <USBHost_t36.h>
uint8_t buf[] = {0xF0, 0x41, 0x10, 0x00, 0x00, 0x00, 0x4D, 0x12, 0x30, 0x00, 0x10, 0x1F, 0x13, 0x0E, 0xF7};
USBHost myusb;
USBHub hub1(myusb);
USBHub hub2(myusb);
MIDIDevice midi01(myusb);

void setup() {
delay(1500);
myusb.begin();
}

void loop() {
midi01.sendSysEx(15,buf,true,0); // No midi activity - lights or data on logger
midi01.sendSysEx(15,buf,true,1);
midi01.sendSysEx(15,buf,true,2);
usbMIDI.sendSysEx(15,buf,true,0); //works fine out the slave port
midi01.sendNoteOn (71, 56, 1);
midi01.sendNoteOff (71, 0, 1);
usbMIDI.sendNoteOn (71, 56, 1); //works fine out the slave port
usbMIDI.sendNoteOff (71, 0, 1); //works fine out the slave port
delay(500);
Serial.println("USB Host Port - Transmitting........");

}
