HI,shoneill,
Thanks, but, assuredly I tried, like what you said, it is fail, then I would come to here to search the help. that kind of handle is very natural for every computer user I think. but it is still not help, the USB port becomes "USB composite Device" after I intall USB VISA RAW, uninstall it, and computer re-search the hardware, and restore what it was again and again.....
