So what you want to do, is try and tell the kernel to release the device: if device.is_kernel_driver_active(interface): try: device.detach_kernel_driver(interface) detached = True except Exception as e: print "ERROR: Could not detach device from kernel:", e You could also try and make sure the kernel doesn't load a module for the device, or use rmmod to remove the module associated with the device.
