The current code prints all wMaxPacketSize content at endpoint descriptor, if there is a high speed, high bandwidth endpoint, it may confuse the users, eg, if there are 3 transactions during microframe, it will print "wMaxPacket 1400" for packet content. This commit splits wMaxpacketSize and transaction numbers for output messages.
