Computer does not recognize card reader

temm me operating system....win xp? win vista? win 7? 8?
card reader driver is from JMicron...

What happens when you tried to plug-in SD card to the computer?

Have you made any recent changes to the computer prior to the issue?

To make the SDHC be recognized by the computer, we need to ensure that the card reader works in Windows 7 first. Please check if the card reader is recognized properly by the computer and you have installed the driver for it.

Meanwhile, you can plug some other storage cards to the card reader and see how it works.

I would suggest you to refer the link below

Uninstall all the Generic USB drivers and reinstall.

1. Open Device Manager.

2. In "Disk Drives" dropdown, uninstall the "Generic SD/MMC USB device" drive.

3. Restart computer.

4. Insert SDHC card.

Hope this helps.

You could, drivers are based on manufacture. Like Realtek is a common maker of audio chips, and sometimes distributors use a popular motherboard.
You may have plateaued at Vista, by try the Troubleshooting Compatibility with Vista 64 drivers before you roll it back.

BTW - This happened to me with Win 8.

Try this link it should have the driver if not you can search the website. Sabrent website does not have the driver:

Hi, what has happened is when you installed the Win 7, it hasn't recognized your Video card, what you need to do, is obtain a driver that is suitable for Win 7. You need to go to the manufacturers website of you Video card,or PC, and find the driver and download and install. If it is an ATI card go to the ATI website and download the latest driver for your video card, if NVIDIA then the same applies here, BOTH of those sites would have a suitable driver, IF the card is supported under Win 7.
Many Video cards are NOT suitable NOR supported, in this case you either have to use the "Generic" drivers Win 7 supplies, or change you Video card if possible.
I have a feeling that your PC will NOT be suitable for Win 7. However I include the link for your drivers. Please go to this website below and download your Video Drivers and see how you go.

Go to the card reader manufacturer's website -- you'll need to download the Windows 7 driver for it.

1. You have to see if the program is compatible with the Windows 7 operating system.
this is possibly due to drivers that the Windows 7 doesn't have in the "cab" files.
this manufacturer of the Dynex is your next step for a Windows 7 driver set.

these types of devices are usually ran by generic drivers, if any are needed at all; its basically an adapter.
Are you sure that your problem is with the drive?

If it isn't too far out of your means, I don't use the software for my camera. I use a card reader. You can find a card reader for about $10 - $15 in most stores that will read 7 or more types of cards. I use my own photo software. Only accessed the disk for the pdf manual. My laptop has a built in card reader. You may be able to find a solution by letting your computer search for a driver on Microsofts site. Mine was automatically recognized on win xp. Hope this helps.
