Hello
I am a beginner in this field and i am doing my 
master. My project has to do with the USB 2.0.
I want to find out which is the data packet size?????
Is it 1,024 bytes or 8,192 bytes???? 
Not the PID and the crc16, just the data.
What's the difference between the usb 2.0 and the 1.0,as 
concern the data again?
Also, which is the duration of a frame size (Full/Low-Speed)(in msec)????

Thank you Giorgos
