SL811HS Enumeration Problem

Hi All,

I am trying to write a firmware to interface USB keyboard with SL811HS(Host) with a help of Atmel AT89c51Rc2 in KEIL , i have some problems with it .

When a keyboard HID device is connected, I have successfully detected the Low speed device connection ...the next step is to get device descriptor. But when i send a setup packet and immediately read the status register i observed "Time out bit set".... How to proceed further ?

Thanks in advance
Sethu
