------------------------------------------------------------------------------- USB HID ------------------------------------------------------------------------------- This is a set of example captures of USB/HID communication on an Olimex STM32-H103 eval board with an ST STM32 (ARM Cortex-M3) microcontroller. The firmware on the board is a simple libopencm3 example named 'usb_hid' which lets the mouse curser move a small amount to the left and then back to the right in an infinite loop.
