I have bought Lenovo Yoga book YB1 X91L almost one year ago, and since first start the device does not see Micro SD card, which I want to use as additional storage. the card isnok - have checked several times in different devices. Windows 10 is showing driver mistake, but can not determine the mistake. I have written to Lenovo support before, they have advised to instll Intel chipset and battery drivers from the web-site, I did, and it didn't work. Soon the guarantee expires, and there is no sulution.

Re: Class controller sd storage driver mistake

Welcome to the Community Forums!

 

Sorry about the trouble. We would like to know if the the SD card reader is even detected in both Device Manager and Disk Management. If the card reader is not detected, try these steps:

 

1. Insert your SD card into the card reader on your laptop

2. Open the Control Panel

3. Switch to the view by Small icons

4. Click the "Troubleshooting"

5. Click the "Configure a device"

6. Click the "Next" button on the popup box to make Windows 10 detect device problem

7. After that, Windows will give solutions to you and you can click the "Apply this fix" to solve the SD card reader issue.

Re: Class controller sd storage driver mistake

I have the same issue with my Yoga Book Win10 Pro (1809). It's ok on my other Yoga Book Android...

There's a issue with driver I think. Device in management windows appears with yellow symbol (error code 10) but any update can't solve it.

 

Hardware is the same between the Android and Windows version I guess, so it's driver issue (Windows or Lenovo...).

 

There's is a kind of solution with RealTek driver, but it's not ok for me.

 

Lenovo Support writes always the same useless solution (troubleshoot) : it's not working.

 

Which part of driver we have to install ? HELP !

Re: Class controller sd storage driver mistake

Exactly! 

The bad thing is that one year has already passed and the solution is not given. Maybe it is a hardware problem? 

I have fullfilled all of the instructions given to me via e-mail, and it did not work. And at the end...well if it didn't help, we have nothing to do with it. 

the device is running on Windows driver issued in 2006. Super - it is 2019 now! 

Well...who cares...
