usb 1-1: khubd timed out - pxa270 - linux.2.6.20

Hi all
    I am facing some strange problem regarding wi-fi 3com adapter on my 
PXA270. khubd detects the device and attaches the driver(zd1211rw.ko) 
too but
gives "hubd timed out" error after loading the required firmwares. I am 
sure that firmwares are loading properly as I included some debug messages
in the driver. Another thing is its not always gives the same error; 
some times ( around 1 out of 3 attempts) it works properly and creats 
eth0 interface.
I am unable to figure it out bcos of this inconsistency. Anybody has 
idea on how to go further.


Thanks in Advance
