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.
Method for cleaning the list of non-devices not used: (Many have already been tested and gives good results when nothing helps "see" a workable USB device. Not me. I just found on the other
the forumAnd designed.)
0. Disconnect all external USB devices from the computer.
1. Create a environment variable named devmgr_show_nonpresent_devices with an equal value 1. To do this:
1.1. Right-click on the My Computer icon and select "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":
5.1 Section "Disk Devices"
Each time you connect a new USB flash drive, a new driver is set. Each time you connect the same USB flash drive, but a new driver is installed to another port.
The drivers of all currently disabled replaceable media in this section can be safely removed - they themselves will be reinstalled when connecting flash drives and other USB media.
Among these hidden and unused drivers will be the driver of your device (possibly "unsuccessful" and not one). Boldly remove everything that applies to your device in this section. When you first connect the device, the new driver will be installed.
5.2 Section "Other Devices"
Here you can delete all hidden (sulfur) devices - these are all your unsuccessful attempts to put something "something." You definitely do not need ...
5.3 Section "Toms Storage Devices"
Here you can delete hidden (sulfur) "volumes of storage devices" - these are "letters" of your flash drives - you do not need them, because Associate anew when connecting a flash drive ..
5.4 Section "USB Universal Serial Bus Controllers":
Here you can delete all hidden (sulfur) devices: a USB storage device, an unknown device and others.
After all these delets, try to re-connect the device. It should be detected as a new device and Windows will set the driver to it. Usually such a procedure eliminates all problems in conclusted USB device drivers.
