Hi
I'm currently developing for integrating MTP_teensy example on my main source.
For neglecting cumbersome library collision, I just created a new project (Teensy 4.1) and tried to run MTP example (Simplied Examples>Example3-simple sd)
Since there is no MTP_teensy library on the project library, I copied and pasted the library what I got from github (MTP_Teensy-main)
https://github.com/KurtE/MTP_Teensy
But there are several errors occurred badly..
1. FS.h: No such file or directory
I could download any FS.h library from anywhere, but before that, I would like to make sure where I need to acquire FS.h library to avoid library collision.

2. USB Type selection
when I tried example_3_simple_sd example code using arduino sketch, I had to change usb type as "MTP Disk (experimental)"
But I don't know what I need to change its mode in platformio environment
Through googling, I got to know that there is an option as usbtype = USB_MTPDISK so i adopted it, but please let me know it's correct or not

3. SD.h vs SDfat.h
Actually, main goal of my project is composed of two things
(1) Saving data in high rate through SDfat.h library
(2) Getting an access to SD card through external USB port
However, if I suppose that I solve the above two issues, I can't avoid worry about coming library collision issue
When I included <SD.h> and <SDfat.h> libraries simultaneously before, It gives an error
I need to sdfat library for my fast data saving, but SD.h is also mandatory required for using mtp_teensy library as i think
Sorry for many asking and thank you so much for helping me in advance
