If you see a yellow exclamation mark here, the chip is not faulty; the driver is either corrupted (rare) or a BIOS setting is incorrect.
Before downloading any driver, you must correctly identify the hardware IDs.
If you are searching for this driver because a COM port is not working, follow this logic tree:
Symptom: A Serial Port (COM & LPT) entry in Device Manager has a yellow warning. Action: asmedia asm1083 serial port driver windows 10
Example: A PCIe serial card containing an ASM1083 bridge + a MosChip 9865 serial controller:
Windows 10 has a vast built-in driver library, but support for legacy bridge chips is not always perfect. Specifically:
The most common error codes you will see in Device Manager include: If you see a yellow exclamation mark here,
Without a properly functioning driver, your legacy PCI cards will not be detected by the OS, or the system may experience random freezes when accessing the PCI bus.
If you are short on time, follow this exact sequence:
Cause: Windows insists on using its own generic PCI-to-PCI bridge driver. Solution: Download the driver for that specific serial
Solution: Force driver assignment using the "Have Disk" method with the official ASMedia .inf. You may need to uninstall the current driver first: Right-click → Uninstall → Check "Delete driver software" → Reboot.
Sometimes the bridge is working, but the serial port itself lacks a driver. If your ASM1083 is connected to a physical COM port header:
