7.4.2 and Macbook problem

[amdxmania]

My system is Apple MacBook C2D 2Ghz, 2gb of ram running leopard 10.5.3
I have 002 and M Box 2 that i use and i'm experiencing few problems

I do not have any problem using PT when I use 002 but when i plug in my MBox 2 and try to use PT it can't detect the hardware. When i click MBox 2 in the system preferences, it does not have any problem connecting.... seems like 7.4.1 with CS3 was working best of all so far..

Another problem that i'm encountering is Core drivers not working at all on either devices. 002 works after reboot, but once i disconnect the firewire cable i have to reboot to make it work again. MBox 2 have another problem though- Core drive never can detect the hardware. I guess it's somewhat obvious since PT software can't detect it either..

any known issues for these problems??
Thanks in advanced!!!
