• int libmouse_usb_out_attached() returns 1 if there's midi-out device attached
• int libmouse_usb_read(uint8_t *buf, int size) - tries to read usb data. blocking. max buf size is 64 bytes. returns number of bytes read
• int libmouse_usb_write(uint8_t *buf, int size) - tries to write usb data. blocking. max buf size is 64 bytes. returns number of bytes written
