Topic: FYI: ExpressCard + unpowered Multiface = Digiface on MBP
I routinely unpower my Multiface when I power down my MBP. But if I power up my MBP without powering the Multiface, the drivers read "Digiface" and stay that way even if I subsequently power up my Multiface; audio does not work in this case. Ejecting and re-inserting the ExpressCard resets the system and all is well. Using the "Disconnect" feature doesn't work either.
Just an FYI, in case this minor issue can be addressed in some future firmware/software update.
