[OB] My $.02 's worth.

[Christopher Erickson]

That rings a bell.

I seem to remember having to use external power with most USB devices
because there simply wasn't enough power available in the CardBus connector
to power many of the more power-hungry USB devices like CDROM, DVD, floppy
and hard drives.

My Adaptec USB/Firewire CardBus adapter card had a small power socket on it
so you could feed it external power for power hungry USB devices.
