gpsjunkie,
Cool. Very cool.
I don't know where you got the MSI to install the ADB drivers, but I've been looking for something like this for days.
Verizon, NEC, Casio, and my local salesman were useless wastes of oxygen in this regard.
One thing that was peculiar was when I went into USB debugging mode from Applications | Development, the CASIO CDROM USB Device driver never was found, it just sat there Searching... So far it hasn't been a problem.
I got nothing before. Now I get the expected serial number when I run ADB DEVICES.
