From left to right: micro USB, mini USB, B-type, A-type connector, A-type connector
micro USB - used in the smallest devices like music players and mobile phones;
mini USB - also often found on players, mobile phones, and at the same time on digital cameras, PDAs and similar devices;
B-type - A full-size connector installed in printers, scanners and other devices, where the size does not have a very fundamental importance;
A-type (receiver) - connector installed in computers (or on USB extension cables), where the A-type connector is connected;
A-type (plug) - A connector that connects directly to a computer into the appropriate connector.

What you need to do first

1) Try to replace the cable.
2) Plug into another USB port (preferably behind the system unit, since these ports are soldered directly on the motherboard).
3) Try another PC.
4) Disconnect all USB devices (both external and internal (for example, card reader))

Alternative ways to connect to a PC using third-party programs.

Proper removal of device drivers from a computer
Device drivers are usually hidden in the device manager as soon as the device turns off or gives a command to hide it (despite the fact that they are still installed in the system). Very often, the "same-name" drivers conflict because of inconsistencies between versions, etc.

The method of cleaning the list of unused devices: (Already, it has been tested by many and gives good results when nothing helps to "see" a working "device."
0. Disconnect all external USB devices from the computer.
1. Create an environment variable named DEVMGR_SHOW_NONPRESENT_DEVICES with a value of 1.
For this: 1.1. Right-click on the “My Computer” icon (My Computer) and select “Properties” (Properties).
1.2. In the dialog box that opens, go to the Advanced tab and click on the Environment Variables button.
1.3. On the Environment Variables panel at the top of the dialog box, click the New button.
1.4. In the “Variable Name” field, type (better copy from here) DEVMGR_SHOW_NONPRESENT_DEVICES, and in the “Variable value” field, enter 1.
1.5. Press the “OK” button twice in a row.)

The created environment variable will allow the device manager to show all device drivers installed in the system (both hidden and all that have ever connected to the computer).

2. Call the manager / device manager:
3. Right-click on the “My Computer” icon, select “Properties” (Properties) and go to the “Hardware” tab.
4. Click on the “Device Manager” button, expand the “View” menu and select the “Show Hidden Devices” command.

5. Start "cleaning" the system from the "trash":
Section 5.1 "Disk Drives" Every time you connect a new USB flash drive, put a new driver. Each time you connect the same USB flash drive, but a different USB port, put the new driver. Drivers of all currently disabled removable storage devices in this section, you can safely remove - they put again when connecting flash drives and other USB-carriers. Among these hidden and unused drivers, and driver will be "on your device" (possibly "bad" and not one). It should be called "Your device" USB Device, but it is not always determined correctly and so the name could be more ... Feel free to remove everything that relates to the "Your device" in this section. When you first connect the "Your devices" new driver from the current established himself or ask you to install it.

5.2 Section "Other devices" Here you can remove all HID (gray) devices - these are all your unsuccessful attempts to put "something". You definitely do not need them ...

5.3 The section "Volumes of storage devices" Here you can delete the HID (gray) "volumes of storage devices" are the "letters" of your flash drives - they are not needed, because will be assigned again when you connect a flash drive ..

5.4 Section "Universal Serial Bus Controllers USB": Here you can remove all HID (gray) devices: "Your device" Device USB Driver, USB storage device, Unknown device and others.
5.5 Restart the computer.

6. After all these deletions, try reconnecting “your device”. It should show up as a new device and Windows will install drivers for it or you install them yourself (on some devices you need to install drivers without USB connection, i.e. connect after driver installation).
6.1 Restart the computer.
Typically, this procedure eliminates all the problems in conflicting drivers "of your device."

7. Thank you for the information provided.Alex_1959,: yes2:

Some tips for ownersSamsung
Advice for LGP500 owners (and possibly other phones) with custom / original firmware
ATTENTION!Before all manipulations, save all data and close running programs, since When installing the driver, the system displays a blue screen.
LGP500 CM7.1-N2 + ta-gb-1.3
1. Connect the phone to the PC, the PC does not find the driver.
2. Go to the task manager, look for our device (will be with an exclamation point).
3. Right-click - update-driver-select the installation of the driver from the computer-select the driver from the already installed ones.
4. In the list we are looking for a USB controller; we select a universal one (it may come from small ones as well as others) -component usb device.
5. The system will install the driver, you can use the usb-flash drive function.

Shl. The most important point is 4. The main thing to find in the list is a driver of the type "composite usb device", on xp and 7-k points can be missed. If the system does not fall out of the blue screen (the appearance of a blue screen is very rare, for example, when installing the driver from the drive for usb hub =)).

If issuedblue screenwithout disconnecting the phone from the computer, poking on the reser on the system, the PC will reboot, after giving the choice of loading the operating system, selectSafe mode. The system will boot into safe mode, then start-up control panel-dispatcher device-look for our phone (in my case, the phone had a name like .... LG USB ...), right-click to remove the driver. Reboot.

It is also possible to force the booting into safe mode during the next reboot before all manipulations (in win7 we launch start-in search, enter msconfig - the load tab - put a tick in the Safe mode - click on OK - the system will ask Restart or Logout without rebooting - select Exit without reboot).

ZZY. The method works on 7-ke exactly - checked on the stationary and on the beech (win7x32).
(!!!) P.S. Do not forget that problems with connecting the device to a PC via USB can be caused by:
  • features installed on a specific device, custom firmware;
  • third-party software installed on the device and / or PC, a conflict between them, etc .;
  • The problem may be in the "hardware" (technical malfunction of the memory card, USB-port, wires, etc.).

In the presence of these circumstances, universal methods, indicated anywhere else, may not be of help to you.

After connecting the YUSB cable, you need to pull down the status bar, and in the rolled out curtain, poke into the YUSB connection point. After that, you will have an offer to mount the SD card, or something like that.

Hello. Perhaps not quite on the topic, but also about USB.
We have: tel1- ZTE Libra CM 2.3.5, tel2- SE Xperia X1 WM 6.1, radio with USB input.

When you connect the phone 2 to the radio, it is defined as a USB flash drive and the melodies recorded on the phone card are normally played by the radio tape recorder.
When connecting tel.1, it is also defined as a flash drive, it can be determined from the screen of the radio tape recorder where the inscription Read lights up immediately, but this is not the case.
When you connect both bodies. To BB everything works fine without any differences between tel1 and tel2.

Hello to all.

Similar to my post in the topicThe computer does not see the phone connected via USB(post 27)
Not editable, gives an access error. I ask the moderator to delete the message.

So there is exactly the same problem.

Tablet Mireader 801. New, just sent.
No programs were put, all from the factory.

Android version 2.3.1
Gingerbread build number v 1.28

When connected to someone not found.
Windows HP writes:
One of the detected devices does not work correctly, and Windows cannot identify it ...

We go My computer - properties - equipment - device dipetcher
Section "universal serial bus controllers"
We see the new appeared "unknown device"

- Properties - details
Hardware code - USB \ UNKNOWN
The device code is USB \ VID_0000 & PID_0000 \ 5 & 18EA5B2 & 0 & 2

Drivers are not set.
The same connector on the tablet with the cord-host works. A flash drive is seen through it.
But not sure that everything is smooth here.
It seems that it is seen, but when you turn on in the status bar, there are no messages. Flashing only the music scanning icon and that's it.

There are no inscriptions for safely removing the flash.
But after the flash drive turned off the message pops up
@Removed USBMassStorage. Insert a new one.

I did not do a hard reset, I do not know how it will look like from the point of view of warranty.
Suddenly you have to send back a pill.
