Because we have not enough memory to have each TX FIFO of size at least 3072 bytes (the maximum single packet size with 3 transactions per microframe), we create four FIFOs of lenght 1024, and four of length 3072 bytes, and assing them to endpoints dynamically according to maxpacket size value of given endpoint. Up to now there were initialized 16 TX FIFOs, but we use only 8 IN endpoints, so we can split available memory for 8 FIFOs to have more memory for each one. It needed to do some small modifications in few places in code, because there was assumption that TX FIFO numbers assigned to endpoints are the same as the endpoint numbers, which is not true since we have dynamic FIFO assigning.
