Interesting: when I build msc_disk.c into the tinyusb component itself (specifically, in components/tinyusb/tinyusb/src/class/msc, alongside msc_device.c), it compiles and links with only the error
region `dram0_0_seg' overflowed by 11808 bytes
If I then change the DISK_BLOCK_NUM to 4 instead of 2 * 140, to avoid allocating 70kb of data, it links without any errors. (It may not run because the "disk" is too small, but at least it compiles and links cleanly).

Here's components/tinyusb/CMakeLists.txt file with msc_disk added to it. It's the stock CMakeLists.txt from espressif/esp-idf-master, with one line added to include msc_disk.c. The chegewara version of this CMakeLists.txt is very different: the most obvious change is that tinyusb as added as a library here, not compiled as a "normal" component as it is in the chegewara version. I'm guessing that this is at the root of the problem, but I'll have to learn a lot more about how these builds work before I can figure out how (or if!) I can make msc_disk work in its original location.

Do you have any coding examples that is just simply reading and writing text files to the SD card and then drag/dropping them through the usb without involving usbWeb? Or you do have any good headers on how I can implement that through the code that you already provided? Also, I'm having some trouble compiling the arduino-tinyusb library with the header files. Should I be including espressif/esp-idf and the arduino-esp32 branches as components?
For arduino-esp32 you can use this library:
https://github.com/chegewara/EspTinyUSB

I will try to add new example with msc class using SD card, but for now it requires to edit arduino-esp32 a bit.
Here is last file (dont know why i cant attack it):

This example is using RAM disc, so you can easy decrease DISK_BLOCK_NUM to 2*16 or something to fit in S2 RAM, or you can add few more lines of code to use PSRAM.

I just added sd card msc example to arduino EspTinyUSB library. It still requires to update local SD library in arduino-esp32, but using code later is very easy:
https://github.com/chegewara/EspTinyUSB ... sd_msc.ino

It is very slow to work with big sd card, like 16GB (it takes teens of seconds before you can use card, when you open root folder first time), but its working nicely and with small effort its possible to add "OTA" update with drag n drop.

Do you have maybe "Serial Connected to: USB CDC"?
When you are using USB device (at least with my library) you have to use UART0 for serial logs.

I'll check when I get back home today. Sorry for the long post, couldn't figure out how to make it scrolling. But I'm fairly confident it is UART0 bc I've never used USB as serial before. I see that there was also of "conflict with c linkage" errors and alot of the messages seems to reference webusb.x quite a bit and a couple tusb header files. I have no idea what that means tbh.

After a closer look it seems like these few lines lines are the most relevant for the code failing to compile as everything else seems to be warnings. This is built in the arduino IDE using the V4.2 release of the espressif/esp32-arduino repo.

Ok, it looks like there are some changes in tinyusb merged in most recent commit of arduino-esp32. You can try with this commit, which is working:
https://github.com/espressif/arduino-es ... 79a4ad3e7e

EDIT i just updated library to follow changes in tinyusb API.

it seems like the PC was unable to recognize the the descriptor, so my device is connected as an unknown device. I'm using a usb Micro b connector with the ID pin set as floating. I don't know if this makes a difference. From what I gather, you seem to be using a USB A connector? Would the code work with a usb micro B?

edit: funnily enough, it worked right after i posted this reply, maybe it was just a crappy micro b to usb a cable.
