 		 #135513 - need some help
Responding to: ???'s previous message
I am now using the USB interface for ISP programming of AT89C5131A-M.

Every time I plug-in my board in the USB port of the computer, the following message is displayed

"USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.For assistance in solving this problem, click this message."

On the clicking the message,"Unknown Device" is message displayed.
I have tried updating the driver but it is of no use.

I am using Flip 2.4.6 for ISP programming. I have also installed the USB Auto Launch Software.

But nothing seems work..
someone please help me...
