I use my Motu 828MK3 since 6 Months with my Laptop and the firewire Controller (ricoh) with some little problems but it works good.
Today I plug in my Motu in to the (internal) firewire (Ricoh) and I get an BlueScreen (Windows Vista) and the Laptop reboot immedialy.
After the reboot, the it's the same .
I deinstalle the firewire driver reboot the PC and it's the same (BlueScreen and reboot)
I use an other firwire controller (TI), but the Moto is not found ??? In the past it works good !!
A few days ago I've install the windows vista service pack and today i've install any other vista service updates - if this ist the cause of this problems ?
Can anyone say the same ??
After the deinstalling Vista SP1 the motu is working fine ...

Thank you MS
Kind regards
Michael
