[asking23]

Hi,

I need to use this library with ESP32 WROOM and need to use Pen drive for storing the Data Log files. Can i use this library or need another library ?

Hi,

nope you can't, this library is limited to USB-LS HID devices.

Only an ESP32-S2 or ESP32-S3 will be able to act as a pen drive, and you won't need any external library for that as they're natively supporting USB-OTG.

I want to write log files to Pen Drive. So Need USB Host Functionality.

You need a full usb HOST with USB-MSC support, it still requires and ESP32-S2 or S3 and ESP32-USB-Soft-Host is useless for that as USB-MSC needs at least USB 2.0.

Also I don't know of any host implementation of USB-MSC so you'll probably have to bake you own.

I have no idea how to do that, but I'll be interested by the results of your research, feel free to add more feedback to this post 👍
