"The ASM1083 isn’t really a serial port chip – it’s a PCIe-to-PCI bridge. Windows 10 doesn’t have a specific 'ASM1083 serial port driver' because that’s a misidentification. Go to Device Manager, right-click the problem device, pick 'Update driver' → 'Browse my computer' → 'Let me pick' → choose 'PCI-to-PCI Bridge' from the list. That should clear the error. No need to hunt for an ASMedia download."
