Hi,
I don't tell you how to work with the Palm debugger because I don't use it,
but some thoughts that might help.
First, sysNotifyVolumeMountedEvent can be debugged on the emulator, too.
Some emulators (notably Clie) offer a GUI to simulate card mount/unmount
events. Older OS4 emulators allowed to do it via changing emulator settings.
I gave up device debugging when it stopped working after the Palm desktop
upgrade. It was probably my laziness, but I soon found that those few cases
when the device debugging comes handy can be as a rule mastered by
alternative tools, e.g. logging. It is not quite the same, but it is often
even better. (Not to speak about the problems with the device debugging that
I experienced in the past.)

Get the free application caled DotDot - it will do the switch to the debug
mode for you.
Best regards,
Jan Slodicka

It connects to the PC with a USB cable. But earlier, the documentation says

lowercase L from the graffiti area, I draw a vertial line - nothing like the
symbol that is shown in the documentation. Second, in order to enter a dot
(period), I tap the stylus once - not twice. It seems that this
documentation was written with the original Graffiti in mind - but Tungsten
E uses Graffiti 2.
