Limitations on implementing USB MSC Host

Official Hardware Classic UNO R4 WiFi

Hi All

For my project, although I can go for MAX3421E based USB host shield, but RENESAS R7FA4M1A says that there is USBFS which host mode capability. I want to save data in USB-Pendrive.

Arduino documentation talks about HID class for USB but it seems like there is no work that is done for MSC class. Is there any limitation on implementing MSC class in Host mode? Like I don't want to waste time in trying to implement that to only conclude that there is some technical limitation, otherwise, I am better of with MAX3421E.

Thanks

That's for sure! In several cases we had it limping along.
But I also have not found the inspiration either.

Totally agree. But at this point I punted, first to playing with Arduino GIGA and currently back to playing with Teensy boards.
