remount usb memory

[William Ehrich]

When I have a USB memory plugged in and unmount it in Finder, how can I 
mount it again without physically unplugging it?

No, not really. I'm trying to use a program on Mac Os X. Said program wants to 
do debugging work on another process.

On Mach, that relies on task_for_pid. The security system of Mac Os X makes 
this rely on more than just "same user ID".

None of the applications are sandboxed; none have asked for extra security.

Sometimes it works.
Sometimes it does not.
I cannot figure out any pattern.

The debugger is being started from Terminal, which was opened by launch 
services in response to double-clicking a dock icon.
The execution comes from double clicking a dock icon (eclipse), which in turn 
starts a different program (minecraft) that opens it's own connection to the 
window server.

Everything should be in the same context, with no permission restrictions asked 
for.
Different window server connections should be no different than gdb on an 
appkit program

OK, let me rephrase. I think you posted to a group that has exactly one person 
using JvisualVM.

Perhaps, but I bet there's a lot of people that have run into task_for_pid 
failures, possibly with gdb. And perhaps someone that has a solution that 
doesn't involve codesign on a bundle (since this is not a bundle, but a 
command-line tool.)

Re: remount usb memory

Disk Utility can do this, so I would suspect there are third-party tools that 
could do it as well.
