Help Needed: Firewire Audiophile not working with iMac & OS 10.6.8

Dear all,

After reading the FAQ and forum threads and not founding any valid clue for the troubles I'm experimenting, I find my self forced to ask for some help.

i'm using a M-audio Firewire Audiophile soundcard perfectly on my macbook laptop -see details on my signature- but I'm also trying to use it with my iMac, which has the same operative system -10.6.8, rest of technical details on my signature- and there's no way to plug it and use it propperly.

I've tried installing the drivers -version 1.10.3- several times, I follow the common instructions properly -installing drivers, shutting down computer, plugging the soundcard and turning computer on- but I can't get anything but blinking leds.

I've also tried restart the computer with the blinking leds and crossing fingers to see if it happens, but no positive results so far.

I know the card works perfectly on my laptop, and I just can explain myself why it is not working on my imac despite of using the same OS.

Any help will be really appreciated,
Thank you
