    hello,everyone.I am a newbie to usb, and I am confused by the crc equation.TOKEN CRC :G(X)=X5 +X2 +1,DATA CRC:G(X) = X16 + X15 + X2 + 1. Can anyone tell me the meaning of them and the relation between the two equations and the implementations in the opencore's program.
	thanks a lot for your answer!
