My windows ME worked well with my midi keyboard USB connection,uploading and downloading midi files from floppy,but since I upgraded to windows XP sp2 the connection won't work.I reinstalled the keyboard driver but to no avail. Any suggestions would be appreciated.
So you transfer song files via MIDI? Or use a sequencer to control the keyboard? Do you have any more luck if you try immediately you start using your PC, ie just after switching on. Some USB devices can be switched off automatically by XP if they're unused for a while (saves battery drain for laptops). Finally, do you switch your PC off at the wall when you've finished using it?
