Hi!

If I use remove with a built in card reader or my PC Card to
USB, they won't detect anything plugged into them later until
a reboot.

And that is an interesting and anomalous result! ... Ben Myers

With a built in reader, the result doesn't surprise me. Windows cuts
power to the whole device even if you're just removing one card from
it. At least that's how it works with a Sandisk 8-in-1 USB card
reader. Windows has no way to know the difference between internal and
external USB devices.

Hi William! I have never seen it work any differently.

As far as the PC card reader goes, I have no idea why it would not
work upon reinsertion...

I'll take another look at this. If I pull the PC Card to USB card out
and reinsert it, works once again.

However, I can always just plug it back in and go again.

That is the way the PC Card, USB card readers, and serial (RS232) to USB
adapters all work for me.

The Macintosh does not behave the same way, and keeps the Sandisk 8-
in-1 turned on after ejecting cards.

One workaround that I found was to use the "Eject" command that shows
up on the context menu in My Computer. Right click the relevant drive
letter to see it. This makes Windows commit all the data to the media,
but it will keep your reader active. But I could just as easily pull
the Sandisk from its cradle and stick it back in again.

Ah... I never used eject before. Just for floppies. And that is what the
Mac calls it too? Interesting. I just tried it and it seems to work
great. I'll try it for other things too and see what happens. Thanks
again.

Oh yeah, before I forget. I noticed my USB card readers don't honor the
write protect switch of SD(HC) cards. While my built in card readers do.
One would have thought that this was a function of the card itself, not
the card reader.
