USB error message on tiny6410 kit

Girish
Dear Sir,

        i have been receiving the following error message on hyper-terminal
for the past few days :- 

usb 1-1: device descriptor read/64, error -62

         the kit is not able to detect any kind of USB devices,i have tried
connecting usb mouse and also usb pen drive,both were undetected,the usb
host controller ic onboard has supply +5V coming correct but the buspwred
pin and gangpwred pin are at +2V (pulled up via 1K and 10 K to +5V)and the
voltage at pin no.12 is also +2V instead of +3.3V,are this static voltage
parameters correct??

we are able to find the source for the part having part number :- AU9254
A21,kindly let us know from where can we buy this component,out location is
Mumbai,India.

Regards,
Girish
