Emu XL-7 & MP-7 User's Group

I and others have written about E-Mu usb drivers on XP. I had the hardest time until either SP2 or SP3.  I think Windows changes how composite usb devices were handled. I assume you have SP3.

That being said, if you don't have the usb drivers installed, that shouldn't be your problem.

I do believe several people had problems with specific usb midi interfaces. Possibly some ate sysex, I think.  I would look at the midi monitor in e-loader and see what is going is going on in terms of the communication (if you can do that while in OS install mode--not sure about that). 

I will try to carve out some time to see if I can find related discussions in the archives (unless you already checked there).
