| Does anyone know how to refresh a USB port after selecting safely remove hardware, without unplugging the device (Card Reader) and then plugging back in? |

| I don't know if this works but try opening the device manager and selecting the USB controller and then refreshing. |

| I have this same problem. Instead of searching for the right buttons on my computer I just unplug/re-plug it in |

If this works I'd like to make a button that goes on the task bar or on the desktop or in the system tray. Anybody know how to do that? |

Yeah, this one should work. |

No that does not work. It actually tells me it has been
configured for safe removal and to unplug it and plug it back in.

don't safely remove hardware, and instead, just unplug the device.
i've never had a problem doing that.

if you dont have to safely add it, why would you need to safely remove it?

Well my explanation would be, when you add it there is no power applied to the card until the computer recognizes it automatically from some form of scanning or state change interrupt and adds the new hardware found, then applies power. When taking it out power is applied to the card maybe at the last address of the pictures you just looked at. If you break the connection on the pins it could cause a logic error and corrupt your stuff. So disabling the power before you take it out is a good idea. True you can get away with just pulling it out, better safe than sorry.

i don't use a card reader much( my printer does it ) but when i have, as long as the reader isn't actively reading or writing to the card i don't see it being any different than removing a card from a camera that is still on...
as far devices with power buttons, turn the power off before unplugging.
BTW - i do regularly take the card out of the printers reader slot while the printer is still on as well.

If you have Windows XP, you don't have to worry about plug/unplugging USB devices. This was more of a Windows 98 thing.

weren't they all more of win98 things? ;}

The device doesn't really matter, there is no memory being stored into a
printer or a camera without a "memory card" which is the whole point.
A device just processes the data to and from memory.
One would want to safeguard your memory written on the card from
electrical properties like ESD or EMI.
My cameras instructions state to make sure and turn it off before opening the CF door, as I am sure most others do as well.

this is pretty much the only way, safely, to do it as far as I know.

| This not an answer to the OP's question, but a clarification of the purpose of the "Safely Remove Hardware" button. This is not intended to protect against an electrical spike or such. Rather, this is to assure at all data being written to the device are complete by flushing the write buffer. |

You remove the card from the camera that is still on?? Wow I just assumed this was always a bad thing whether the card is accessing or not. Kind of like changing hard drives or memory in your computer while it's still running.
back to the OP...I seem to remember a device I had that when you went into the properties it allowed you to choose whether you had to use the "remove safely" option or not. Can't remember what it was and not sure if every device offers this. |

My camera is always on when I take the card out. I just make sure the light isn't flashing
