Plugging in the card reader does not reflect, why does the card reader plug in and does not respond?

It's either that you're plugging it in the wrong way, or that there's something wrong with your card reader.

Some chipsets do not have good model compatibility.

You plug it in now, that 1M memory of the phone itself Mobile hard drive shows not?

The portable hard drive (bottom right corner) was not deleted

I pulled out the data cable. Go up in flames.

If there is a driver in the driver, try it! ~~

Microsoft has a service related to this, you see if your service is over-optimized.

When the card reader has a fault that cannot be recognized, there are many cases of damage, which is manifested by the fact that the computer does not respond, because the card reader itself is a wearing part, and damage is common. In this case, the card reader is discarded and replaced.

If your card reader is inserted with an SD card, it may be that the card reader is broken, so change the card reader; If you use a microSD (TF card) plus card sleeve to convert to SD card, insert the card reader and can't read it, it may be that the card sleeve is broken, and change the conversion card sleeve of a MicroSD to SD card, and it is not excluded that the card reader is broken.

Plug in a USB flash drive to try it, if the computer can read the USB flash drive, it means that there is a problem with your card reader or memory card, if the USB flash drive cannot be read, it may be a computer system failure, reinstall it and it will be ko.

Answer hello According to the information you provided, I found for you that this is generally because the card reader is not in good contact after oxidation, so use an eraser to erase it. If the eraser doesn't work, or you don't want to change the card reader, it's because the memory chip on your card should be burned, and the card reader can't be recognized, so change the card. The card reader is not responding.

Or maybe your card reader has a lot of ports, and the port without the card is clicked on this reaction. If there is only one port, it means that the card is not plugged in tightly, and some of the contacts are not touched. The card reader is not responding.

Try a different card reader, if it doesn't work, it's a problem with the computer.

I often encounter this problem, you have to see the situation, most of the current card readers have small lights, after plugging in, regardless of whether the computer is connected to the display or not, the lights should be on, if you plug in how to fiddle with the lights are not on, basically the card reader is broken, don't look for any software problems, if the lights are on, you go to find software problems, update the driver, or restart the computer, or plug in a different port, to be honest, the life of the card reader is quite short, many general card readers are broken after a year or two, I'm talking about the case of regular use.
