In fact Brandon does not use an mbed board but a Landtiger board with an lpc1768 and a regular RS232 serial port. That board does not use an FTDI USB serial converter so you dont need that driver unless you have an adapter cable for your windows pc to convert a USB port into a regular RS232 serial port for the Landtiger. Virtual Serial Port Driver 8.0.412 Download Virtual Serial Port Driver is a simple application that allows you to create virtual COM port pairs. Virtual serial ports created in Virtual Serial Port Driver behave as if they were real ports, so applications can communicate with each other and transfer data via virtual null-modem cable.
Summary :
COM ports are common components of Device Manager. Windows users can see them easily by opening the Device Manager. However, problems may occur, causing the COM ports lost from Device Manager. If you are encountering this, please read the methods mentioned below to try to fix the problem yourself.

Two: No Ports shown in Device Manager (even hidden) Win 7 Pro 64 bit.
I can't get an external modem to work (even though it shows in devices and printers window. I can't get a USB-serial port converter to work either. It would be helpful if I had info from the device manager window but nothing show up, even though I have turned on the show hidden devices. Any ideas? Thanks.- asked Paul Saacke in Microsoft Forum

How Do I Add a COM Port to Device Manager
Some users complained that their Widows 10 COM ports disappeared from Device Manager after they have upgraded their Windows platforms. Whatever the cause, the users’ primary concern is how to restore missing COM ports. That’s what I’m going to talk in this section.

Method 1: Show hidden devices.
As I have mentioned at the beginning of this article, users can’t see the COM ports directly. Instead, they need to open Device Manager -> select View tab -> choose Show hidden devices. After that, they’ll see the Ports (COM & LPT) option and they only need to expand it to fins COM ports.
Method 2: add COM ports manually.
- Open Device Manager on your Windows 10 computer.
- Click on the Action option from menu bar.
- Choose Add legacy hardware from the submenu to open the Add Hardware window.
- Click on the Next button to move on.
- Check Install the hardware that I manually select from a list (Advanced) and press Next.
- Select Ports (COM & LPT) from the given list and press the Next button.
- Choose Standard port types option or the manufacturer for the ports; then, click Next.
- Click on the Finish button to complete.
Method 3: update the motherboard drivers.
If the motherboard drivers are too outdated, they will also lead to COM ports missing in Device Manager. Therefore, you are advised to update your motherboard drivers manually and see whether it works.
With bridged networking, Oracle VM VirtualBox uses a device driver on your host system that filters data from your physical network adapter. This driver is therefore called a net filter driver. This enables Oracle VM VirtualBox to intercept data from the physical network and inject data into it, effectively creating a new network interface in software. When a guest is using such a new software interface, it looks to the host system as though the guest were physically connected to the interface using a network cable. The host can send data to the guest through that interface and receive data from it. This means that you can set up routing or bridging between the guest and the rest of your network.
Even though TAP interfaces are no longer necessary on Linux for bridged networking, you can still use TAP interfaces for certain advanced setups, since you can connect a VM to any host interface.
To enable bridged networking, open the Settings dialog of a virtual machine, go to the Network page and select Bridged Network in the drop-down list for the Attached To field. Select a host interface from the list at the bottom of the page, which contains the physical network interfaces of your systems. On a typical MacBook, for example, this will allow you to select between en1: AirPort, which is the wireless interface, and en0: Ethernet, which represents the interface with a network cable.
Bridging to a wireless interface is done differently from bridging to a wired interface, because most wireless adapters do not support promiscuous mode. All traffic has to use the MAC address of the host's wireless adapter, and therefore Oracle VM VirtualBox needs to replace the source MAC address in the Ethernet header of an outgoing packet to make sure the reply will be sent to the host interface. When Oracle VM VirtualBox sees an incoming packet with a destination IP address that belongs to one of the virtual machine adapters it replaces the destination MAC address in the Ethernet header with the VM adapter's MAC address and passes it on. Oracle VM VirtualBox examines ARP and DHCP packets in order to learn the IP addresses of virtual machines.
Depending on your host operating system, the following limitations apply:
Mac OS X hosts. Functionality is limited when using AirPort, the Mac's wireless networking system, for bridged networking. Currently, Oracle VM VirtualBox supports only IPv4 and IPv6 over AirPort. For other protocols, such as IPX, you must choose a wired interface.
Linux hosts. Functionality is limited when using wireless interfaces for bridged networking. Currently, Oracle VM VirtualBox supports only IPv4 and IPv6 over wireless. For other protocols, such as IPX, you must choose a wired interface.
Also, setting the MTU to less than 1500 bytes on wired interfaces provided by the sky2 driver on the Marvell Yukon II EC Ultra Ethernet NIC is known to cause packet losses under certain conditions.
Some adapters strip VLAN tags in hardware. This does not allow you to use VLAN trunking between VM and the external network with pre-2.6.27 Linux kernels, or with host operating systems other than Linux.
Oracle Solaris hosts. There is no support for using wireless interfaces. Filtering guest traffic using IPFilter is also not completely supported due to technical restrictions of the Oracle Solaris networking subsystem. These issues may be addressed in later releases of Oracle Solaris 11.
On Oracle Solaris 11 hosts build 159 and above, it is possible to use Oracle Solaris Crossbow Virtual Network Interfaces (VNICs) directly with Oracle VM VirtualBox without any additional configuration other than each VNIC must be exclusive for every guest network interface.
When using VLAN interfaces with Oracle VM VirtualBox, they must be named according to the PPA-hack naming scheme, such as e1000g513001. Otherwise, the guest may receive packets in an unexpected format.
