I just bought back the 15 Xinnai multi function card reader, why didn t it respond when plugged into

It's inherently bad, and I've done it there. Because of the large quantity, sometimes in order to ship, the boss will ask the bad ones to be mixed together and sent out, and Xinnai has no quality at all, the wages are low, and no one can be recruited, so it is sent to the villagers to assemble, all of which are packed in baskets or boxes, thousands of them in a box, and they are packed together, and the good ones are pressed into bad ones; Moreover, some things obviously can't be used, the boss can use them to assemble them with a word, and the bad ones can also be shipped, and the quality is the boss's final say, not the quality; You go to the workshop to know, 5S is not done, it is a handicraft workshop, there is garbage on the ground, the products are piled on the table, messy, there are more than 30 assembly workers, the workers are all remembered, the workers only pursue quantity, do not care about quality at all. Not to mention the warehouse, expired components, expired shells, have not been dealt with, crowded warehouses, there are quality problems, because the first business is a friend of the boss, the same use, some things have expired for a year or two, as long as there is, they will be used, there is nothing of quality or quality.

And the boss is very charlatan, and he dresses like a peasant. Only care about profits, not about quality.

I took it.

If you buy it, someone else will teach you.

Confirm whether there is a problem with the U s B socket on the computer, usually there is more than one U s B interface in a notebook or desktop, so change the card reader to two sockets and try it, if the reading is successful, it means that there is a problem with the U s B interface of the computer before, if it is not successful, it means that the card reader is a little problematic.

1. To check whether there is a problem with the card reader, if the card reader cannot be read on a computer, then try it on another computer, if it still can't be read, and these computers can successfully read the U disk information, that is the card reader problem.

2. Because the card reader is inserted into the memory card, check whether the position and way of inserting the card in the card reader are correct to ensure that all postures are correct, especially to distinguish the front and back of the card insertion.

You first delete the card reader driver on your own computer, then plug the card reader back in, and you're good to go.

The socket of the computer is not in good contact, or it is not recognized by the card reader!

Is there something in the card reader?,If you put it, it's not good to touch.。

Alas, mine is also a problem. The memory card is still on the phone, indicating that the memory card is not broken, the card reader was just bought, the last time I bought one, it was broken a few times, this time the boss said that this is very durable, I thought to myself, I don't know what the problem is, the last time I plugged into the computer, some words popped up I didn't pay attention to it and accidentally closed the window, and I still don't know what the problem is.

The card is not easy to break. It's the card reader that's broken, so let's get another one.

Maybe it's a problem with your card reader.

If the card reader is fine, why is the light not on?

It looks like the card reader is broken, try a different card reader.

It could be that the card reader is broken!

Check the contact problem first, and try to see if it can be on other computers. If it can be contact, or drive, if it is contact, change the interface, and replug it a few times. For drivers, go to Device Manager, find the driver to delete, and then replug it.

If it doesn't work, there may be a problem with the card reader, or the card is locked. In particular, the mobile phone card can be locked in the mobile phone, and it can only be read if it is unlocked on the mobile phone. No more, sorry, card problem.

It could be that the computer doesn't recognize the hardware or memory card. It is recommended that you try a different memory card or a different computer. It shouldn't be a card reader's business. Unless, unless you get water into the card reader. Ha ha.

First of all, it's not an interface problem, because you can plug in the mouse, and if the card is fine, it's a broken card reader. This one is broken a lot.,It's enough to buy a 30 to 40 multi-purpose card reader.,Thank you.。。。

One is poor contact, the second is broken, and the third is that you look at a small button on the left side of the card reader, dial it up and down, and plug it into the computer at the same time to see if there is any response!

It should be a broken memory card or card reader, otherwise the card reader has a bad contact, and you can replace the card reader if you can't plug it in a few more times, hoping to solve your problem.

There are two possibilities for this.

First, your memory card has a password added to your phone, which can only be read on your phone. Removing the passcode on your phone will do it.

This is the most likely. You can consult the webmaster of the Internet café.

In the desktop My Computer Properties Device Manager, then plug in the card reader, then a gray driver item will appear in the Device Manager, start it, if this does not solve the problem, try to test the interface if there is no problem.

It must be the reason for the card reader. I used to be like this, maybe it was not properly operated during use, so sometimes it can be read and sometimes it can't, just change it.

Check first to see if there is a problem with the card reader, especially if a small contact in the card reader is misplaced. When the memory card is inserted, this contact is pushed upwards.

Change to another card reader that can be used to try the card to see if it can be read, if it can mean that it is a problem with the card reader, the card reader is inexplicably broken, you are unlucky.

One: The card reader is not easy to use.

Two: There is something wrong with the memory card.

3. The computer plug-in does not support the card reader to run.

It may be that your computer does not have a driver for the card reader installed, and the next driver wizard will update it.

This has nothing to do with not deleting it safely, it is estimated that your card reader cannot recognize the card, or the card reader is damaged.

The average card reader is easy to break, basically broken.

If you pay 10 yuan a piece, there is no need to repair it. Just buy it.

It is possible that the card reader is dusty, has poor contact, or the card reader is broken, or the card is broken.

Sure the card reader is broken.,I went to buy it last time.,Wow,,The boss just entered the batch of goods,,It's all subordinate.。。。 Later he gave me the one he used...

Look at the cards... Now the card... On the same level as the card reader...

It's possible that your card reader is broken.

Or there's something wrong with the slot.

It can display the installed driver, indicating that it can be detected, there may be a driver problem, and the next U disk driver can be used.

Maybe there's something wrong with the system.,Generally can't read it and won't be as green as you said.,And restart,Reinstall the system and it should be fine.。

No driver, you can install a driver wizard.

It could be a quality issue with your card reader. I've come across it before, and sometimes I can read it.

The card reader will not respond until the card is plugged in on the computer.

If the card does not respond, it is possible that the card or card reader is damaged.

It is possible that the computer is slow, and there is a possibility that the driver is lost.

Plug it in a few more times, remember not to pull it out directly, and then pull it out after deleting it.

Have you tried a new card reader? I think it may be that the card reader is broken, that thing is easy to break, the voltage is unstable and it is easy to burn it out, I changed two or three directly a month, and then I directly chose to use a data cable to connect directly to the computer up and down things, but also convenient, and do not use a card reader!

When buying a card reader, it is best to let the salesperson try it on the spot, sometimes the internal quality of the card reader is not good, it will not be read, the first time I bought the card reader is like that, and finally I have experience, I can rest assured after trying it on the spot.

Let's see if it's a disk issue or an excuse issue.

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.
