After checking up-to-date PCI ID repositories:
The device appears as a but creates multiple COM ports and one LPT port in the OS.
Wait – careful: CC_070005 means:
WCH (Nanjing Qinheng Microelectronics Co., Ltd.) - DeviceHunt Vendor ID 1C00. DeviceHunt WCH PCI Express=>DUAL SERIAL Driver for System
: Identifies the Vendor ID for Nanjing Qinheng Microelectronics (also known as WinChipHead or WCH ).
The ID 1C00 is sometimes attributed to or listed as "Reserved / Vendor-defined" in older PCI databases, but actual hardware with this ID overwhelmingly points to PCIe to multi-I/O controllers from MosChip (now Asix Electronics) or Netmos designs.
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
