Had a good look around and found many different ideas,but none seem to fix the problem totally. At a guess,i would expect a reinstallation of SP2 would cure this,but why install a 260MB pack for a file probably of 20kb.
Someone may be able to find the file,sadly i cannot find the file at the moment.
Thank you Skidzy, this particular item is rather important to me since I employ it after doing some in-depth work with a professional G70 Roland keyboard. Recently, and since it disappeared, I have had to just jerk out the USB terminal and of late, have been having problems in both the KB and the PC. However, the workround is great and now well employed. Thank you again.
