    V850ES/Jx3-U - Plug it! Endpoint 0 is the endpoint for control transferring. However, standard device requests,such as the request used by enumeration for plug-in, are automatically responded by hardware. Therefore, this should monitor standard requests that are not responded by hardware, class requests, and vendor requests. Endpoint 0 Monitoring Process Start Check CPUDEC Interrupt...
