Hi Yuuichi, I'm trying to send midi messages to a Nux mg-300 (modeling guitar processor). When I run USB-MIDI descriptor I get this:

If I try to send a message

`void loop() { Usb.Task();

if ( Usb.getUsbTaskState() == USB_STATE_RUNNING ) {

if ( Midi ) 
{

 uint8_t buf[3];

buf[0] = 176;
buf[1] = 60; 
buf[2] = 1;
int test = Midi.SendData(buf);

 Serial.println(test);

}

} delay(1000);`

I get this error: USB_ERROR_INVALID_MAX_PKT_SIZE

i saw maxpktsize is 0, i tried to comment the code and now i have error 4.

`uint8_t USB::OutTransfer(EpInfo pep, uint16_t nak_limit, uint16_t nbytes, uint8_t data) { uint8_t rcode = hrSUCCESS, retry_count; uint8_t *data_p = data; //local copy of the data pointer uint16_t bytes_tosend, nak_count; uint16_t bytes_left = nbytes;

    uint8_t maxpktsize = pep->maxPktSize;
    //if(maxpktsize < 1 || maxpktsize > 64)
    if(maxpktsize > 64)
            return USB_ERROR_INVALID_MAX_PKT_SIZE;`

Could you help me? am I doing something wrong?

Thank you
