Dual-Core USB Host (HID) and USB Device (CDC)

Question asked by Steven Pearce on May 21, 2018

I need help implementing a USB HOST and USB DEVICE with the ST USB library.

(They do not need to be OTG)

I am trying to integrate the Device CDC standalone and Host HID standalone application examples.

My merge has the mouse working with USB HID FS, but only the first ASCII text from my PC is received and responded to by the EVAL board on the USB HS (CDC VCP peripheral); subsequent text is ignored.

Can anyone help please?

(I am using an STM32H7531-EVAL board primarily, although I also have an STM324x9i-EVAL board)
