After checking up-to-date PCI ID repositories: → Asix Electronics Corporation (formerly MosChip Semiconductor). Asix acquired MosChip's PCIe/PCI I/O controller line. Thus, the actual vendor is ASIX Electronics / MosChip . 3. Device Identification (DEV_3253) DEV_3253 corresponds to:

| 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 | pci\ven_1c00&dev_3253&cc_070005

| Vendor | Details | |--------|---------| | (or Silan Integrated Circuit Co., Ltd.) | A Chinese semiconductor company. However, this specific vendor ID is also widely reused by PLX Technology (now part of Broadcom) for bridge devices, and by various third-party PCIe-to-serial/parallel bridge chips under the MCS (MosChip Semiconductor) or Oxford Semiconductor families. | After checking up-to-date PCI ID repositories: → Asix

This device is a common consumer chip; it's targeted at industrial automation, POS systems, embedded PCs, and expansion cards for legacy printer/serial device support. 4. Class Code Analysis (CC_070005) The PCI class code 07 00 05 breaks down as: However, this specific vendor ID is also widely
