Windows Driver Package - VSO Software (pcouffin) VSO devices is a low-level Windows driver installed by VSO Software’s disc-burning applications, such as ConvertXtoDVD, CopyTo, and BlindWrite. Known as the “pcouffin” driver (pcouffin.sys), it provides direct, reliable communication with optical drives (CD, DVD, and Blu‑ray) to enable advanced reading, writing, and drive control features beyond standard system APIs. The package typically includes the driver, INF, and catalog files, and may appear in Device Manager under “VSO devices.” It runs in the background, has no user interface, and loads only when required by VSO applications. The driver is safe when obtained from official VSO installers. If you no longer use VSO products, it can be removed by uninstalling those applications or by deleting the related driver entry.
Windows Driver Package - VSO Software (pcouffin) VSO devices is developed by VSO Software. The most popular version of this product among our users is 1.3.
