: If the installer fails, right-click the device in Windows Device Manager , select Update Driver , and browse to the folder where you extracted the WCH files.

If you are encountering this ID in a Device Manager error log: pci\ven_1c00&dev_3253&cc_070005

This is a device, typically found on industrial motherboards, embedded systems, or PCIe add-on cards providing legacy I/O ports.

| Field | Value | |-------|-------| | | MosChip MCS3253 / ASIX AX99100? (or similar) | | Chip family | PCIe to dual UART + parallel port controller | | Function | Adds legacy I/O: 2 x RS-232 serial ports + 1 x IEEE1284 parallel port | corresponds to: : If the installer fails, right-click

The MCS3253 is a specific part number from MosChip (pre-ASIX acquisition). Later ASIX equivalents: (PCIe to multi-I/O, software compatible).

You will most commonly see this ID in under "Other Devices" or "PCI Serial Port" when the system cannot find a compatible driver. This happens because standard Windows installations often lack the specific UART drivers for WCH chipsets. How to Install the Driver (or similar) | | Chip family | PCIe

However, in many multi-function PCI devices, the reported may be 0x078000 (Other comm controller) or 0x070002 (parallel port). But here CC_070005 appears inconsistent.
