Subject: [usb] USB1.1 Low Speed Issue---HELP!!
Hi dear,
I have tried this IP at 1.5 Mhz clock I have got the Setup packet
Succesfully , but in responce to the next IN token when i m sending the
DATA1 its not sending ACK back.
Its right that there is no logic written for the LOW SPEED in the TX_PHY
module but by slight changes u can do that.
thanks
regards
Govind
