Although driver calls in the API do not return an error message, the data that is returned seems to be random. This was tested e.g. for bulk-in transfers, where the tested USB device should return certain data. The number of bytes delivered by the device is correct (so basic USB communication seems to work) but the data is corrupted. defect closed other VirtualBox 1.5.2 obsolete USB other other
