This category collects official and legacy VIA IrDA drivers for systems using VIA infrared controllers — the software pieces that let laptops, motherboards, PCMCIA/ExpressCard modules and add-on PCI/USB IR ports communicate over infrared (SIR/FIR). Available files include signed installers, INF driver packages, firmware updates and small utilities for testing and configuring speed/mode.
Downloads are provided as direct links to installers or ZIP archives with checksums and release notes. Before installing, verify the hardware ID in Device Manager and pick the matching package. Installation typically requires uninstalling any old driver, running the supplied setup or using “Update driver” and pointing to the extracted INF, then rebooting. Older installers may need Windows compatibility mode; modern 64-bit systems require signed drivers.
Compatibility information and version history are listed on each download page. If connectivity fails, check BIOS IR settings, enable the port, and confirm IR protocol (SIR/FIR). Create a system restore point before changing drivers.
