pxa270 - USB low speed devices - Maybe the USB cable is bad?

Dear All,
    I am working on pxq270 board. Its up with linux-2.6.20. Currently I 
am working on USB modules. For Full speed
devices ohci driver is able to detect and attach the proper driver. But 
for low speed devices its giving "*hub 1-0:1.0: Cannot enable port 1.  
Maybe the USB cable is bad?"* error. I have gone through the mailing 
list found no relevent solutions. The device (USB keyboard) works fine 
with Normal PC (linux-2.6.16).
