Hello ; 

I tried to read the reference manual but still not clear ; 

is it possible to use  USB FS ( GPIOA ) and USB_ hs ( FS mode) ( GPIOB) at same time in host mode ?

in our applicstion we need two host USB to communicate with 2 USB flash ( FATFS) 

Thank you 

Regards

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.
