[Answer]:
1, this problem may be that the computer is not equipped with "ergonomic input device".
Right-click the desktop shortcut My Computer, click Properties, and then click Hardware. At this time, you can see "Device Manager" in the first column. Click Device Manager to view the Universal Serial Bus Controller and Unknown Devices. Click the right mouse button after finding it, and then click "Update Driver".
2. If it still can't be used after the above operations, you can choose "uninstall" first and then reinstall. Pay attention to complete unloading when unloading. The so-called complete uninstall means that after adding/removing programs, you have to go to Windows to find a separate file and delete it. Then reinstall the yawei system.
3.USB may be turned off in the computer BIOS settings, just turn it on.
Boot—-DEL enters BIOS—- finds USB—- turns it on.
4. HP, ASUS, Lenovo notebooks If the USB man-machine input device is normal, the screen may not be displayed, and a program needs to be uninstalled under the man-machine input device in the device manager.
For example:
HP -CQ 35 1 Uninstall Enecir Hid Subdevice 00.
HP-6330 and HP-54 1 Uninstall the HP Quick Start button.
Hp-—V3000 uninstalls Hp remote control HID equipment.
Lenovo -—Y430 unloads ENECIR receiver.
Lenovo -—Y450 uninstalls ITecIR infrared receiver (EC)
Note: After the computer is restarted, these programs will be automatically restored and need to be uninstalled again.
