Change subject: fix ASFv4 USB stack
......................................................................
fix ASFv4 USB stack
this ASFv4 USB library change fixes USB transfer.
two transfer-size issues existed:
- on multi-packet transfer if the last packet was less than the
USB transfer packet size, the packet would be received but not
acknowledged
- during normal transfer the packet size of a previous packet set
the size of the current packet, ignoring the actual transfer size
