Solved internal multi-card reader opens and closes independently

April 24, 2012 at 07:28:25
Specs: Windows 7, 2gb
What is making my multi card reader open and close by itself with or without a card or flash drive inserted. This is a generic "all in 1" with a 2.0 usb port mounted internally on a desk top running Windows 7? Device driver report is the latest drivers are installed and they are working properly.

The card reader runs on USB power. Either the device is drawing too much power, or is not being supplied enough power from the USB port. And you hear the USB insert and remove sound, Right?

Try to reseat the cable or try a different USB header on the mainboard.

If not then you are talking about why you can't see your card reader in explorer.

Open an explorer windows, hit the alt key, click on tools, folder options, view. Now un-check "hide empty drivers in the computer folder"

"And you hear the USB insert and remove sound, Right?"

Dong ding (a lower tone then a higher tone) when a USB device is plugged in, ding dong (a higher tone then a lower tone) when it's unplugged.

"Try to reseat the cable"

The most likely thing is you have a loose connection.

If this card reader is on the front of a desktop computer, open up the case by removing the left side panel as seen from the front of the case.

REMOVE the AC cord from the case.

There may be a single connector with multiple wires, 4 or 5 wires, or individual connectors on each wire, 4 or 5 of them, on the pins of a mboard USB header.

There may or may not be a wiring connector or connectors at the back of the card reader as well. The wiring connector(s) may have been loosened on that end.

"This is a generic "all in 1" with a 2.0 usb port "

It should have two sets of 4 or 5 wires, for the pins of separate USB ports on the USB header. One set only for the USB 2.0 port, the other set only for the card reader.

If it has only one set of wires for both, the USB 2.0 port will NOT support you using an external hard drive or an external optical drive with it because they require the full max USB spec 500 ma from the port, but it will work with anything else.
In that case, if you have an external hard drive or an external optical drive plugged into the USB 2.0 port, one of, or both of, the external drive or the card reader will NOT work properly.

Troubleshooting can't get a memory card to be recogized properly, in Vista (the same things probably apply to Windows 7; similar applies to XP and 2000).

Detail about how you determine if the card reader and card are being detected properly, what Windows should do but might not do.
.....

The circuitry of older memory card readers cannot recognize newer larger capacity memory cards, or types of memory cards that first came out after the card reader was made, at all.

Okay, thanks to you folks that responded. Tubesandwires was given "best answer" status because it was an in depth reply. Gretti was pretty much the same answer and would probably given me enuf info... so thanks to both of you.

I had done all the basic steps, checking the wire seating and pulling the item and reinstalling it before looking for help. Nothing worked. And there were no other 9 pin unused usb port terminals on the motherboard. However, taking into consideration what was advised, what I did was switch the oem wiring with the add-on multi-card reader on the mobo. As a result, I opening and closing, at least so far today, has stopped (cross our fingers). Every port and usb on both the oem and the add-on are working fine. So for me its a "go figure." Why would just swapping wires around make a difference? .... thanks again to you both for the help.

The initial diagnostics is always the hardest. Elaboration on an answer is not an answer. But glad you got it figured out.

...well maybe all isn't right... seems the original problem has ceased but I have lost the ding-dong of the device opening and closing on the add on. Without the "computer" window open I'm not sure if the device is continuing to open and close since it don't ding-dong no more. The oem continues to work normal, sound and all on the new terminal.

You should hear the dong ding, ding dong when you plug in things, unplug them from / into USB ports, including the USB port in the card reader, EXCEPT FOR the internally connected card reader if it has a good connection to it's USB port pins on the header (you don't need to plug it in, unplug it) .

You don't get the dong ding, ding dong when you plug in / unplug a memory card into / from the card reader.

When I plug in a thumb drive, into any usb port on my machine, I get the ding dong, including the new multi reader. However, I get no sound at all when plugging in an SD card. The computer reads the card, I can save and delete on the card, but there is no ding dong either when plugging in or unplugging. It does appear the inadvertent opening and closing has stopped with the new configuration, ie, switch around of wiring ports, to the transfer of info seems stable. I could live with that except without the sound and the problem having been intermittent, I can't be sure it has stopped unless I leave computer icon tree displayed. Again, this new multi reader is a replacement for one which was malfunctioning, so unless I have two bad ones, it would seem I have an internal problem stemming from the motherboard.

Your situation is now as it should be.

"You don't get the dong ding, ding dong when you plug in / unplug a memory card into / from the card reader."
.... whether the card reader is externally or internally connected to a USB port, if the card reader is already connected and has a good connection.

Since you're not plugging in / unplugging the internally connected card reader, you're not going to get the dong ding, ding dong from that, when it has a good connection to the pins for one USB port on the USB header.

You SHOULD get the dong ding, ding dong when you plug in / unplug something into / from the USB port on the internally connected memory card reader. That should be connected to the pins on a USB header for a different USB port from that for the card reader device - if it isn't you have an inferior combo device .

You SHOULD get the dong ding, ding dong when you plug in / unplug an external card reader into / from a USB port
