Hello,
Thanks for the help below. I am trying to answer "what will the
keyboard send me if I send it a packet configured over
USB_SPEED_FULL?". Simply setting usb_device->speed to USB_SPEED_FULL
doesn't work as the packet does not even get sent by the
subsystem/hcd.
Would you have an idea how I can at least send the packet over the wire?
Thanks,
Gabriel
