Hi,

I have no actual experience in coding USB,so I cant answer exact questions about it,

but I believe that you need to run a single USB Host 'supporting all classes' connected to a USB HUB.

then you can have 2/3/4 USB Flash Drives and or a mouse or printer if you want to.

Hi

‌,

Indeed. You may use the two USB peripherals on GPIOA and GPIOB simultaneously.

Khouloud.
