Windows® Device Drivers

Device drivers are the software interfaces that talk directly to the physical usb controller hardware. The PCI\VEN Code can be broken down into parts that relate to the hardware manufacturer, the category of the hardware and the revision of the hardware. The first part, the "PCI\VEN_", is specific to the manufacturer, OPTi® has the PCI\VEN code of "PCI\VEN_1045". The "&DEV_" part of the code relates to the hardware, in this case the "DEV_C861" relates to usb controller hardware, specifically the 82C861. If the usb controller device is slow or just seems to be not working, then it is likely that the driver is a generic driver, is not installed correctly or is just broken. For use only with the OPTi® 82C861 device, an up-to-date list of downloads is shown below.
