Description

Describe the bug
Sending MT3 messages to UM-ONE running with the USBMidi2.sys causes Green Screen.

This issue only occurs if I call the 'send-file' command via the Windows batch file.

To Reproduce

  1. Set the Roland UM-ONE to class-compliant mode (set the switch to "TAB") and attach it to PC.
  2. Update the driver to the USB MIDI 2.0 driver (UsbMidi2.sys).
  3. Run 'midi.exe enum ep' and put the endpoint name of the UM-ONE into the attached batch file(Send_MT3-file.bat).
  4. Double click the batch file to run.

Green screen occurs.

Expected behavior
No green screen issue occurs.
