John,

Similar story here for awhile. I have had to unplug the power then re-power, and then both the audio and midi sides of the device become apparent to Windows. Not a sure thing upon first power on. I also have it on a power strip to function as a power switch.

The DAW I'm running is a 32 bit app, in Win7 64 environ, and one other thing I've found that for the DAW software to reliably see the interface I have to run the DAW app as administrator.

BTW - I put a request in with TASCAM today to provide more workable Win7 drivers, without the need to power on after, reset latency each time on power on, etc.

We'll see if I get a canned response from them or if they are really trying on this one.
