Always use your AXE027 USB cable in the same USB port on your computer. It will then always retain the same 'virtual COM port' number. Always insert the AXE027 USB cable before starting the PICAXE software. More details can be found in the Setting up your AXE027 USB download cable for first use page of our Getting Started section. 2.4G USB Aeromodelling FMS Simulator is An essential entry cable combinations. It can work for windows 7 and XP systems. This simulator cable can work with unencrypted simulation software only. The resolution is 1024, the input is a USB input. Note: FMS software is not compatible with Windows 10. Drivers are provided for various versions of Windows. Download and install the correct version for your computer’s configuration before proceeding. Now connect a USB cable between a USB port on your PC and the USB interface module you are using. Windows should report a new device has been found and proceed to initialize it. Free Virtual Serial Ports is a software COM port emulation utility for Windows platform. Our freeware virtual serial port tools kit allows you to create virtual COM ports and connect them into pairs using software-based virtual null-modem cables. It also allows the use of named pipe technology to connect the created port to a serial application. Download Windows USB 2.0 Drivers Updates. Usually USB 2.0 means a faster connection speed and this is the major difference (generally but not always) between USB1, USB2 and USB3, with the latter providing super speeds of up to 5Gbps. Like all drivers, USB drivers are updated regularly and should be kept up-to-date with major changes or updates.
The USB side of the adapter behaves like a standard USB joystick (HID-Device).Therefore you don't need a driver for Windows or Linux (tested with Windows XP, Windows 7 and Ubuntu 9.10).In Mac OS it should work well too, but this is not yet tested.The adapter is ideal for use with a model aircraft simulator on the PC.
PPM
Most R/C remote controls provides a so-called PPM-signal.It consists of a pulse train with about 0.4 ms long pulses.The time interval tn between the pulses corresponds to the stick-positionof each channel. A time of 1.5 ms corresponds to the center position,1ms is the minimum and 2ms is the maximum position.A pulse train consists of n+1 pulses - for 5 channels thus 6 pulses. The pulse train is repeated every 20ms (50Hz).

Hardware
Bild 4: The schematics of the PPM2USB adapter
The circuit is quite simple and can be build on a breadboard or on a perfboard.The resistors and Zenerdiodes provide the USB-required voltage levels.The PPM signal is connected directly to the ICP-pin of the ATmega8.This works with signal levels from 1.5-5V.For the right timing an external 12MHz crystal is used.
Note: The ISP circuitry for programming the controllerwas left in the schematic way.
PPM2USB with USBASP-Hardware
It is also possible to modify an USBASP-Dongle: USBASP to PPM2USB-Modification.
Software
The software was developed with the AVR-GCC tool chain and consists of three parts:
PPM decoder
The PPM decoder is completely interrupt driven.To measure the time, a 16 bit timer is used which is directly connected to the CPU clock (12MHz).
USB stack
Usb Simulator Cable Drivers
The ATmega8 has actually no USB interface. However, it is possible to implement such in software.For this purpose the free USB stack called V-USB is used.
Main program
In the main program V-USB is initialized. Then the controller goes into ainfinite loop and transfers new joystick positions to the PC. It will only transfer data when the stick positionshave changed. This is indicated by brief flashes of the LED.

Usb Simulator Cable Drivers Windows 10
Versions supported
- Windows 10
- Windows 8.1
Applies to
- Device manufacturers of CDC Control devices
Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device.
In Windows 10, the driver has been rewritten by using the Kernel-Mode Driver Framework that improves the overall stability of the driver.
- Improved PnP and power management by the driver (such as, handling surprise removal).
- Added power management features such as USB Selective Suspend.
In addition, UWP applications can now use the APIs provided by the new Windows.Devices.SerialCommunication namespace that allow apps to talk to these devices.
Usbser.sys installation
Load the Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device.
Note
If you trying to install a USB device class driver included in Windows, you do not need to download the driver. They are installed automatically. If they are not installed automatically, contact the device manufacturer. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows.
Windows 10
In Windows 10, a new INF, Usbser.inf, has been added to %Systemroot%Inf that loads Usbser.sys as the function device object (FDO) in the device stack. If your device belongs to the Communications and CDC Control device class, Usbser.sys is loaded automatically.You do not need to write your own INF to reference the driver. The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows.
USBClass_02
USBClass_02&SubClass_02
- If you want to load Usbser.sys automatically, set the class code to 02 and subclass code to 02 in the Device Descriptor. For more information, see USB communications device class. With this approach, you are not required to distribute INF files for your device because the system uses Usbser.inf.
- If your device specifies class code 02 but a subclass code value other than 02, Usbser.sys does not load automatically. Pnp Manager tries to find a driver. If a suitable driver is not found, the device might not have a driver loaded. In this case, you might have to load your own driver or write an INF that references another in-box driver.
- If your device specifies class and subclass codes to 02, and you want to load another driver instead of Usbser.sys, you have to write an INF that specifies the hardware ID of the device and the driver to install. For examples, look through the INF files included with sample drivers and find devices similar to your device. For information about INF sections, see Overview of INF Files.
Note
Microsoft encourages you to use in-box drivers whenever possible. On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. Unlike desktop editions, it is not possible to load a driver through an external driver package. With the new in-box INF, Usbser.sys is automatically loaded if a USB-to-serial device is detected on the mobile device.
Windows 8.1 and earlier versions
In Windows 8.1 and earlier versions of the operating system, Usbser.sys is not automatically loaded when a USB-to-serial device is attached to a computer. To load the driver, you need to write an INF that references the modem INF (mdmcpq.inf) by using the Include directive. The directive is required for instantiating the service, copying inbox binaries, and registering a device interface GUID that applications require to find the device and talk to it. That INF specifies 'Usbser' as a lower filter driver in a device stack.
Flysky Usb Simulator Cable Driver
The INF also needs to specify the device setup class as Modem to use mdmcpq.inf. Under the [Version] section of the INF, specify the Modem and the device class GUID. for details, see System-Supplied Device Setup Classes.
For more information, see How to use or reference the Usbser.sys driver from universal serial bus (USB) modem .inf files.
Configure selective suspend for Usbser.sys
Starting in Windows 10, Usbser.sys supports USB Selective Suspend. It allows the attached USB-to-serial device to enter a low power state when not in use, while the system remains in the S0 state. When communication with the device resumes, the device can leave the Suspend state and resume Working state. The feature is disabled by default and can be enabled and configured by setting the IdleUsbSelectiveSuspendPolicy entry under this registry key:
To configure power management features of Usbser.sys, you can set IdleUsbSelectiveSuspendPolicy to:
'0x00000001': Enters selective suspend when idle, that is, when there are no active data transfers to or from the device.
'0x00000000': Enters selective suspend only when there are no open handles to the device.
That entry can be added in one of two ways:
Usb Fms Simulator Cable Driver
Write an INF that references the install INF and add the registry entry in the HW.AddReg section.
Describe the registry entry in an extended properties OS feature descriptor. Add a custom property section that sets the bPropertyName field to a Unicode string, 'IdleUsbSelectiveSuspendPolicy' and wPropertyNameLength to 62 bytes. Set the bPropertyData field to '0x00000001' or '0x00000000'. The property values are stored as little-endian 32-bit integers.
For more information, see Microsoft OS Descriptors.
Develop Windows applications for a USB CDC device
If you install Usbser.sys for the USB CDC device, here are the application programming model options:
Starting in Windows 10, a Windows app can send requests to Usbser.sys by using the Windows.Devices.SerialCommunication namespace. It defines Windows Runtime classes that can use to communicate with a USB CDC device through a serial port or some abstraction of a serial port. The classes provide functionality to discover such serial device, read and write data, and control serial-specific properties for flow control, such as setting baud rate, signal states.
In Windows 8.1 and earlier versions, you can write a Windows desktop application that opens a virtual COM port and communicates with the device. For more information, see:
