| Problem | Likely Cause | Troubleshooting Steps | | :--- | :--- | :--- | | | Faulty hardware, BIOS settings, or power issue | 1. Reseat the Card : Power down and open the computer, then firmly reseat the expansion card into its slot. 2. Check BIOS : Ensure the PCIe slot is enabled in the BIOS/UEFI settings. 3. Test a Different Slot : Try a different PCIe slot to rule out a slot issue. 4. Verify Card Functionality : Test the card on another known-working computer if possible. | | Yellow Exclamation Mark or Code 10/31/28 | Driver conflict, corruption, or incorrect driver | 1. Force Driver Reinstall : Follow Method 4 (Clean Installation) above. 2. Roll Back Driver : In Device Manager > device Properties > Driver tab, click Roll Back Driver if the problem started after an update. 3. Check for Windows Conflicts : If recently installed Windows updates are causing the issue, you may need to uninstall them. | | The Card Works Intermittently or Causes System Instability | Power management or hardware interrupt conflicts | 1. Disable Power Saving : In Device Manager , open the properties for the COM port (under "Ports (COM & LPT)"), go to the Power Management tab, and uncheck "Allow the computer to turn off this device to save power". 2. Check for IRQ Conflicts : While rare on modern systems, check the device's resource settings in its properties for conflicts. This may point to a deeper hardware issue. | | Driver Installation Fails with "Data Invalid" or Other Error | Corrupted system files or installer | 1. Run System File Checker : Open Command Prompt as an administrator and run the command sfc /scannow to repair corrupted Windows system files. 2. Disable Driver Signature Enforcement : As a temporary measure, restart Windows and select "Disable Driver Signature Enforcement" from the advanced startup options. This can allow an unsigned driver to install but is not a permanent solution. |
[Guide / Solved] How to get the ASMedia ASM1083 Serial Port working on Windows 10
However, a common frustration among Windows 10 users is the dreaded yellow exclamation mark in Device Manager next to the "ASMedia ASM1083 Serial Port" device. This indicates a driver problem. While this chip is over a decade old, it is still widely used, and getting it to work properly on Windows 10 requires specific knowledge. : Some users find success by manually selecting
A: Not if you have no devices connected to the PCI slots that are routed through this bridge. However, Windows will still show an error unless you disable the device or hide it.
If you experience yellow exclamation marks in Device Manager or data corruption, follow these steps to refresh the connection interface. Method 1: Windows Update Right-click the and select Device Manager . Expand the System devices section.
Why? Because Microsoft intended the native pci.sys (PCI driver) and serial.sys (Serial port driver) to handle this bridge. However, due to changes in the Windows 10 driver stack (especially concerning legacy Plug and Play), the native drivers often fail to assign proper memory resources or IRQs to the ASM1083. You will see "Windows cannot verify the digital
If you have a PCI card plugged in (e.g., a sound card), it should now appear under .
The ASMedia ASM1083 is a PCIe to PCI bridge chip, not a traditional standalone serial port controller. Windows 10 often mislabels its generic driver requirement as a "Serial Port" device in Device Manager when the correct PCI Bridge driver is missing.
If possible, move the PCI card to a different slot to trigger a new IRQ assignment. Legacy Hardware Limitations
