Windows POS terminals are typically equipped with multiple USB ports, allowing it to connect to various peripherals simultaneously and maintain efficient store checkout operations. However, there are instances where a Windows POS terminal may fail to recognise a USB device. This issue can arise for various reasons. UiPOS has summarised some common causes below.
1. The USB port on the Windows POS terminal may become deformed due to prolonged use, dust accumulation, or physical damage, preventing it from properly recognising USB devices.
2. If the “Allow the computer to turn off this device to save power” option is enabled in the “Power Management” tab, the Windows POS terminal may fail to recognise the USB device.
3. Windows POS terminals require the correct drivers to recognise USB devices. If a yellow exclamation mark appears in the Device Manager, this indicates that the driver may be missing or corrupted.
4. The USB ports may be disabled in the BIOS/UEFI settings of the Windows POS terminal.
5. An outdated Windows operating system or an outdated BIOS/firmware version on the Windows POS terminal may cause USB compatibility issues.
6. Certain malware may disable USB ports or tamper with drivers, leading to device recognition failures.
If you encounter a situation where a Windows POS terminal cannot recognise a USB device, try the following steps in order:
1. Change the USB port or test the device on another system to rule out physical damage. Also, check whether the “Allow the computer to turn off this device to save power” option is enabled. If it is, disable it.
2. Update the driver. If updating does not resolve the issue, right-click on the device in Device Manager, select “Uninstall device,” and then restart the Windows POS terminal.
3. Check the USB port settings in the BIOS/UEFI of the Windows POS terminal, ensure they are enabled, save any changes, and exit.
4. Update Windows and the BIOS to improve system stability and compatibility.
5. Perform a security scan to rule out potential malware or virus interference.
