How much will the AVR USB load the CPU ?
Is HID or CDC change that load ?

AVR-USB needs the CPU as long as there is USB traffic. This is > 90% os the time if bulk endpoints are involved (as with CDC mode). For all other modes based on control transfers, it depends on how fast you respond to requests. As long as the host polls for a response, there's a lot of USB traffic.
