Accessing files in USB device that's listed on lsusb command

Question

I'm under wsl on Windows 10 19043.1826, so I don't have the "wsl --mount" command so i found out that I could use usbipd to get the USB device 'inside' linux on wsl (Ubuntu 20.04).

then finally I get, and using command lsusb I got the answer:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 303a:80aa Espressif Franzininho WIFI w/Wroom
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After a long hours searching I "found the device" on /dev/bus/usb/001 folder and if I do a ls command on that I get the "files??" 001 and 005, as I understood (I think - wrong) my USB device is that 005

My device (that on Bus 001 Device 005 with ID 303a:80aa) has a file called "code.py" on root of USB device (and device is under FAT) and I want to access this file and root folder. How shold I do that?

I tried

mkdir /mnt/e
sudo mount --bind /dev/bus/usb/001/005 /mnt/e

but didn't work

I found a script here: https://unix.stackexchange.com/a/634849 But didn't understood how to use that I tried to put script on a file getdevice.sh (with nano), saved, and then tried to run

bash getdevice.sh 303a:80aa

but have nothing on response

I'm really asking here because I'm stucked literally for hours on internet seaching and trying a lot of things, and I believe this should be simple to access and I'm missing something.

with the command:

 lsblk -o model,name,size,fstype,label,mountpoint

I get only block devices I think:

MODEL            NAME  SIZE FSTYPE LABEL MOUNTPOINT
Virtual Disk     sda   256G
Virtual Disk     sdb   256G              /

Answer 1

The device /dev/bus/usb/001/005 is not for mounting - it is for sending & receiving essentially raw USB data packets, preferably using libusb or similar.

If the USB device is identifying itself as a standard USB storage device, then it would normally appear as some /dev/sdX device, where X = some letter. As suggested by sudodus, use the lsblk command to see if such a device is available and associated with your Espressif Franzininho WIFI w/Wroom. If your USB device contains just a single filesystem with no partition table (the so-called "superfloppy" configuration), you could mount it with a command like:

mkdir -p /mnt/e
mount /dev/sdX /mnt/e

But if the device includes a partition table, and you wish to mount the first partition, you'll need to add the partition number to the device name:

mkdir -p /mnt/e
mount /dev/sdX1 /mnt/e

But the Espressif Franzininho WIFI w/Wroom is not a USB storage device. It's a development board - a tiny computer on its own, with a WiFi interface and other ways to connect things to it, so it can be used as a building block in hardware projects.

It could be programmed to act as a USB storage device, or as a multi-function device with USB storage being just one of its functions. But since it has just 4 MB of flash memory, it would be a hilariously low-capacity USB storage device unless extra flash memory chips have been added to it.
