That's what happens with my USB sticks, USB disks and another
USB device when connected to MS Windows (Vista and 98SE). When
told to "Safely Remove" (Vista terminology) the OS checks that
the device is not in use by any process or program and, if
necessary, writes cached data to the USB storage and
"disconnects" the device from the OS. The power to USB devices
is permanently on. It is not switched.

For some value of "not switched". When I got my iPod and
realized that it continued charging after (soft) ejecting it, I
leapt to the conclusion that I could probably suspend the
laptop (which was plugged in) and it would continue to do so.
Turned out not to be the case.

Not laptops, indeed, but my desktops' USB power remains on when
the computers themselves are switched off, but still connected
to the mains.

Yes indeed. I usually bring my computer from hibernation by
pressing the space bar or moving the mouse, both USB. It won't
work if the machine has been shut down, though.

That's bringing it back from Stand By. Coming back from
Hibernation requires pushing the computer's On button.

Nope. Hibernation. I don't do standby, which leaves stuff in
memory.

True, but Hibernate shuts down your machine. Anyway, that's how my
Win XP machine works.

An option with a longer perspective is hibernate. Like Stand By, you
can recover your place. The big difference is that your PC has shut
down and is not pulling power. Another difference is that your data
is saved to your hard disk and not RAM. This makes it a safer, but
slower option for shut down and resume.

Hibernate will save your desktop and open files to a special Windows
file called hiberfil.sys. This large file usually resides in your
root folder (c:\hiberfil.sys). The file size closely matches how
much RAM your PC has installed. If you have 2 gigs of RAM on your
notebook, you're going to have to give up 2 gigs of hard disk space.
Note: You can delete the hiberfil.sys file only if you disable
hibernate.

When you press your power button, Windows will start and open the
files you were using. The process is not instantaneous as with Stand
By, but gets you to the same place. You may find this option is
faster than rebooting, as Windows doesn't have to do things such as
detecting your hardware.

Yep, that's exactly what it does. Mine will come back from
hibernation with a touch of the power button, and also with any
interrupt from a USB-connected device. Since I have masked off all
such interrupts in BIOS I suspect it's a BIOS bug, but I find it
handy.

I see. I had a problem when I had a phone line connected to my computer modem. Whenever the phone rang, the computer would come to life from a full shutdown. I'm pretty sure it was a wrong default setting somewhere that I had not corrected, but I just disconnected the phone line from the modem to take care of it.
