In this section you’ll find a curated collection of less-common port drivers for devices that use dedicated interfaces: USB‑to‑serial (FTDI, Prolific, Silicon Labs), virtual COM/LPT adapters, RS‑232/RS‑422/RS‑485 chipsets, FireWire/IEEE‑1394, Bluetooth RFCOMM stacks, infrared (IrDA), CAN bus, I2C/SPI bridge modules, Thunderbolt/docking port replicators and other specialty bridge or modem ports. Each entry includes the driver package, file types (EXE/INF/ZIP/DMG), vendor/version, and SHA256 checksum or digital signature when available.

Download links are labelled by OS and architecture so you can choose Windows (32/64‑bit, Server), macOS and common Linux distributions (deb/rpm, DKMS). Installation notes cover automatic installers, manual Device Manager/Update Driver steps, modprobe/insmod and dkms build instructions, plus rollback and uninstall tips. Compatibility tables list supported OS builds and hardware IDs—check those before downloading to ensure stable operation. Use the included release notes and troubleshooting tips to resolve common port recognition and baud/routing issues.
