USB Host Stack for Zephyr

(1/1)

unscripted:
So Zephyr does not currently support a USB Host stack for Mass Storage Class which I need for my STM32 project. Has anyone worked in porting other stacks like TinyUSB to Zephyr? Or STM32Cube USB Host Library? Any recommendations?

voltsandjolts:
Zephyr has a new experimental usb stack which includes mass storage support.

AFAIK, that's USB Device support, not USB Host.


--- Quote ---This sample app demonstrates use of a USB Mass Storage driver by the Zephyr project. This very simple driver enumerates a board with either RAM or FLASH into an USB disk.

Which I think it is not what I'm looking for. I'm looking to enumerate an external USB flash drive.

Sorry, I skim read your first post and missed the keyword 'host'. Twice. My bad.
