Card reader device driver reinitiation

<p>Hello all. After we transfer files to our computer from a card (compact flash in this case) we have to "eject" the card to safely remove it. This evidently turns off the power to the card reader. If I want to put another card into the same slot to transfer more pictures, how do I initialize the card reader again so that the computer recognizes the card has been inserted? Of course, restarting the computer reinitializes the card reader but I wonder if there is a faster way with a computer command. I am using Windows 7 Professional. Thanks.</p>

<p>Are you using an external card reader or one that's incorporated into your computer in some way? I've used external card readers -- from several manufacturers -- and never had this happen.</p>

<p>If it's an external reader (USB/Firewire) unplugging the cable then plugging it back in should do the trick.</p>

<p>None of my card readers behave that way. And I "Eject" them every time.</p>

<p>My computer gets confused about that sometimes too. I just unplug the USB cable and then plug it back in, and the computer recognizes the card reader again. No need to reboot the computer.</p>

<p>I am putting the card into the computer card reader. I have used a USB card reader before and found that THAT particular USB port is off and can't be used again, but since I have many that is not a problem. I assume the computer devise controller in some way switches off that particular slot or port.</p>

Ejecting the card doesn't turn off power to the USB port. What it does is instruct Windows to flush the cache. In other words to write anything it may have pending in memory and close all connections to that card.

 

if your computer doesn't recognize another card by simply inserting it, you have something going on.

<p>I have never had to "eject" a card reader to remove a CF card before inserting a new card. I just pull out the CF card and shove a different card into the reader. As Fernando states "you have something going on" In regards to your USB port - I use a "Plugable USB 2.0 10-Port Hub" I have 4 USB External Drives hooked up to it and when I need to - a USB Card Reader - never had a problem (I am running Windows 7 Ultimate). You should look into why that USB port can't be used - Software setting issue? Hardware issue?</p>

<p>Try to eject only one card and not entire reader.<br>

Readers with multiple slots assign separate volume letter for each, in Windows.<br>

Then you know what letter is assigned to each reader slot, and eject only that card, while other cards/slots could remain unaffected.</p>

 

<p>This behavior has been true since I bought this computer 5 years ago. I believe it was the same on the prior computer. As far as separate card slots, yes if I use a CF card first I can then put in one SD card and have the computer pick it up. One read per slot seems to be the norm. Again, not a problem, just a curiosity.</p>

<p>Wow. 9 responses and this very minor thread is at the top of the list of active topics in digital Darkroom. Everyone on vacation?</p>

<p>I found that I had the Nikon software- Transfer NX set to disconnect automatically after transferring pictures. Removing that preference fixed the issue. I guess "hot" connect and disconnect is not a problem for CF or SD cards</p>
