    Bulk in packet size





      I'm trying to read data from GPIF and send to host through bulk in endpoint. However ,I found that the bulk in packet size needs to be multiple of 4 bytes, i.e. 3 bytes will result a zero length packet and 5 bytes will result a 4 bytes packet. But the bulk out packet size is actual as that sent from host (PC). Why?
