A digital multi-meter (DMM) contains a microcontroller that will be interfaced to a computer using USB. The computer software needs to be able to configure the DMM and read the values displayed on the DMM. It will also be possible to update the DMM firmware over the USB connection. Suggest a set of USB endpoints for this interface. For each endpoint give the type and the direction. You do not need to include Endpoint 0 (the mandatory control endpoint used by all devices.)
