Wow, thanks a lot.  That is all good information, even if it is a little disappointing :(   It is a shame that a 'standard' protocol varies so much among manufacturers/chipsets.

So, I guess the easiest fix is to buy a firewire ExpressCard with a TI chipset for the laptop?  According to Presonus, a StarTech EC13942 should do it:


If I do go that route, should I then disable the onboard (Ricoh) firewire device?  I'm not exactly sure how to do that - would I do it in the BIOS and/or elsewhere?

Does it also make sense to disable the onboard sound (HDA Intel), or does it not really matter?  

Thanks again for the info!
