Removing Devices from USB Ports

1. Is it best to turn off the computer before plugging devices (e.g. digital

cameras and MP3) in to the USB port and then restart it if the devices are

only going to be 'attached' for a short period or can they be plugged in

while the computer is still on?



2. Generally, if someone is limited on their number of USB ports and they

want to 'unplug' a device and 'replace' with another device for only a little

while, is it best to turn computer off or is it okay to 'unplug' and 'plug'

in again while the computer is still on?



3. If a device is plugged in and the software is installed, the software

will remain installed even if device is unplugged but if it is being plugged

in for the first time, the software for it will have to be installed-Is that

correct?



Thanks!

No, a restart is not necessary. Yes, they can be plugged in while powered

up.

It's perfectly OK to plug and unplug with the devices and the PC powered up.

If it's a USB pen drive or another type of external drive, it's a good idea

to use the "Safely Remove Hardware" icon.

If the device requires software, yes, it will be installed on the first

plug in. Subsequent usage won't require a re-installation of that software.



The whole idea behind USB devices is the convenience of being able to plug

and unplug the devices without having to shut down or restart the PC.

Same as above--yes.

If it needs software. Not all USB devices do.

It depends. Sometimes things are not what they seem to be.

1. USB devices in general are designed as 'hot pluggable'. It shouldn't

matter whether the computer is on or off, or whether the USB device is

powered on or off (such as a printer).

2. People don't generally have a clear idea of what "USB device" means. For

example, many desktop computers have a set of memory card reader slots.

This set of slots is often one "USB device". No slot is a USB device; it

may be just a part of a USB device. You might have memory cards in none or

some or all slots. Each slot will typically show up as separate drive

letters in 'my computer'. On many computers, the memory card's label

appears as the name of the drive. When you want to remove one of the memory

cards, you should first right click the associated drive and choose eject.

When the drive label reverts to 'removable drive', it is safe to pull out

that memory card. Of course, whether or not the memory card's label appears

as the drive name varies from one computer to the next, so sometimes you

can't really tell by the drive label whether the card can be safely pulled.

So you might instead use 'Safely Remove Hardware', which will pop up a

message when it is safe to pull the memory card. The downside is that it

disables the entire USB device, meaning, it disables all the memory card

slots. In this case, the only way I know to reenable the memory card slots

is to reboot the computer.
