Windows 10: Sandisk Card Reader not detected in Windows 11 Solved

The Sandisk MobileMate USB 3.0 Reader I just opened was not detected by Windows 11. The USB Drive F would flash for a millisecond then disappear. For those who want to solve this problem, try the following steps:1. Leave the reader in the USB port.2. Use the search bar and type with no quotes "Disk Management"3. Look for a drive that says "No Media." Eject that drive.4. Pull the card reader from the USB port, then plug back in. It may show on your drive screen now.This worked for me, but as with such Percussive Maintenance-type fixes I don't know how it worked. I found a thread called

CAC Card reader not detecting the card

Hello, I've read several posts with the EXACT same question, but they're not resolved, so I'm starting my own. I'm in the military and use a CAC CARD reader to access websites. After a recent windows update, my computer no longer detects my CAC CARD. The
card reader is fine, but the card itself isn't detecting. I REPEAT, the card reader is fine. (Also, its NOT an SD card. Its a CAC card. On an other post here, a fix was suggested for an SD card. Its not an SD card).

The card reader is detected, I've updated and reinstalled the driver multiple times. I've tried rolling it back. The card reader shows on the computer under Device Manager, it shows on other computers too, and the CAC Card works on other computers. It is
not a problem with the card reader, or the card, it is a problem with some settings in this computer. Internet explorer, google chrome, and firefox all fail to see the CAC Card on this computer. Can you please help fix how my computer will detect the card
itself?

The card reader i'm using is called "Stanley Global Technologies" and in Device Manager it shows as Smart Card Reader- "Alcor Micro USB Smart Card Reader".

Thanks!

Hi Micheal,

Thank you for posting your response.

I would suggest that you check the list of 2.0 Card Reader for Genesys provided in the link below and let me know if it matches the model number of your card reader.

Micro SDHC card does not get detected on Windows 10.

Hi. I tried to mount my Sandisk 16gb micro sdhc card in my phone but it wasn't detected. I tried to see if I needed to format it or something through my Transcend USB 3.0 card reader, but the card is not detected by my computer at all. The card reader is
recognized as disk drive E: in both device and disk management. I don't know what other steps to take.
