Like this: usbDisconnectBus(usbcdc_cfg.usbp); // A delay is inserted in order to computer sense the change chThdSleepMilliseconds(2000); usbStart(usbcdc_cfg.usbp, &usb_cfg); usbConnectBus(usbcdc_cfg.usbp);

In my case I added a chThdSleepMilliseconds(2000); after disconnect, but I don't know if this is necessary in this #define.
