Yes, the midi_interrupt_op is where the IRQ's should be enabled and = disabled. The module will call this. In your driver, I think you also enable Midi transmit IRQ's as well( = EMU_INTE_MIDITXENABLE ). I don't think this is required. I will take = a closer look at what I changed in the emuxki because I just made a few = quick changes, and will email you privately. =20 Greg >i did a change to emuxki.c hoping this will prevent the behaviour you = found. > >i don't understand the "And then enable the midi receive interrupts, >EMU_INTE_MIDIRXENABLE" >isn't the job of midi_interrupt_op to enable these interrupts ? >Bye, >J=E9r=F4me
