     * <b>usb</b>: When the usb keyword is used, the API will work with

     * not work with these. In this case, use a VirtualHub or a networked YoctoHub (see below).
     *
     * <b><i>x.x.x.x</i></b> or <b><i>hostname</i></b>: The API will use the devices connected to the
     * host with the given IP address or hostname. That host can be a regular computer
     * running a <i>native VirtualHub</i>, a <i>VirtualHub for web</i> hosted on a server,
     * or a networked YoctoHub such as YoctoHub-Ethernet or
     * YoctoHub-Wireless. If you want to use the VirtualHub running on you local
     * computer, use the IP address 127.0.0.1. If the given IP is unresponsive, yRegisterHub
     * will not return until a time-out defined by ySetNetworkTimeout has elapsed.
     * However, it is possible to preventively test a connection  with yTestHub.
     * If you cannot afford a network time-out, you can use the non-blocking yPregisterHub
     * function that will establish the connection as soon as it is available.
     *
     *
     * <b>callback</b>: that keyword make the API run in "<i>HTTP Callback</i>" mode.
     * This a special mode allowing to take control of Yoctopuce devices
     * through a NAT filter when using a VirtualHub or a networked YoctoHub. You only
     * need to configure your hub to call your server script on a regular basis.
     * This mode is currently available for PHP and Node.JS only.
     *
     * Be aware that only one application can use direct USB access at a
     * given time on a machine. Multiple access would cause conflicts
     * while trying to access the USB modules. In particular, this means
     * that you must stop the VirtualHub software before starting
     * an application that uses direct USB access. The workaround
     * for this limitation is to set up the library to use the VirtualHub
     * rather than direct USB access.
     *
     * If access control has been activated on the hub, virtual or not, you want to
     * reach, the URL parameter should look like:
     *
     * http://username:password@address:port
     *
     * You can call <i>RegisterHub</i> several times to connect to several machines. On

 * <b>usb</b>: When the usb keyword is used, the API will work with
 * devices connected directly to the USB bus. Some programming languages such a JavaScript,
 * PHP, and Java don't provide direct access to USB hardware, so usb will
 * not work with these. In this case, use a VirtualHub or a networked YoctoHub (see below).
 *
 * <b><i>x.x.x.x</i></b> or <b><i>hostname</i></b>: The API will use the devices connected to the
 * host with the given IP address or hostname. That host can be a regular computer
 * running a <i>native VirtualHub</i>, a <i>VirtualHub for web</i> hosted on a server,
 * or a networked YoctoHub such as YoctoHub-Ethernet or
 * YoctoHub-Wireless. If you want to use the VirtualHub running on you local
 * computer, use the IP address 127.0.0.1. If the given IP is unresponsive, yRegisterHub
 * will not return until a time-out defined by ySetNetworkTimeout has elapsed.
 * However, it is possible to preventively test a connection  with yTestHub.
 * If you cannot afford a network time-out, you can use the non-blocking yPregisterHub
 * function that will establish the connection as soon as it is available.
 *
 *
 * <b>callback</b>: that keyword make the API run in "<i>HTTP Callback</i>" mode.
 * This a special mode allowing to take control of Yoctopuce devices
 * through a NAT filter when using a VirtualHub or a networked YoctoHub. You only
 * need to configure your hub to call your server script on a regular basis.
 * This mode is currently available for PHP and Node.JS only.
 *
 * Be aware that only one application can use direct USB access at a
 * given time on a machine. Multiple access would cause conflicts
 * while trying to access the USB modules. In particular, this means
 * that you must stop the VirtualHub software before starting
 * an application that uses direct USB access. The workaround
 * for this limitation is to set up the library to use the VirtualHub
 * rather than direct USB access.
 *
 * If access control has been activated on the hub, virtual or not, you want to
 * reach, the URL parameter should look like:
 *
 * http://username:password@address:port
 *
 * You can call <i>RegisterHub</i> several times to connect to several machines. On
 * the other hand, it is useless and even counterproductive to call <i>RegisterHub</i>
 * with to same address multiple times during the life of the application.
