UsbDk can't work after plugging out the compound device being directed unless you closes the redirected handle of the device. This issue can be reproduced every time.
The compound device with some USB hubs and one composite device of Camera. Use usbdkcontroller -r to redirect this camera and then plugging out the compound device with hubs. Use usbdkcontroller -n to list current devices and the redirected camera still exists unless you stop the redirection of the camera.
