Is it possible to write a USB MSC HOST driver for the STM32F070 MCU? I see that ST doesn't provide MSC support in the HAL. I also see there are no specific Host FIFOs like the F4 or H7 has. Thanks..Keith Rhodes

No, the USB module in 'F0 is Device-only, no support for Host.

OK, thanks. Do you happen to know the lowest USB MSC Host compliant MCU in the STM32 line?

It *appears* from the datasheet that the F102/F103 support it, but I haven't looked at the software yet to be sure...

Thanks...Keith

You have to look for OTG_USB. In 'F1 it's in 'F105/F107; then in F2/F4, F7/H7, and in the higher-end 'L4.
