Find network adapter ID for youbot driver on Windows

While on Ubuntu the network adapter have simple names like "eth0", on Windows they are more complex. We provide a very simple program that lists the available network adapters under Windows, so the correct one can then be used for the youbot driver. The program just calls the pcap_findalldevs_ex() function of the PCAP libraries and lists the results.

This program called list_pcap_devices is hosted at Github.

In order to run it:

  • Download and unzip resp. checkout the repository into any folder.
  • Start the file runCMake.bat in the project root folder, e.g. by double-clicking it in the file browser.
  • If successfull, this will generate a file "(project_root)/built/list_pcap_devices.sln".
  • Open that file with Visual Studio and compile (e.g. choosing menu Build/Build Solution, or pressing F7)
  • Run the program
    • In Visual Studio, in the Solution Explorer Window right click on "list_pcap_devices" and from the context menu select "Debug/Start new instance"
    • Or start "(project_root)/build/Debug/list_pcap_devices.exe" from file browser or console
  • The program should output the list of devices that can be used with the WinPcap driver. Exit the program with pressing any key.

An example output is the following: 

1. rpcap://\Device\NPF_{0DEBFE06-6009-4A3A-91D1-2540A7065F8B} (Network adapter 'Microsoft' on local host)
2. rpcap://\Device\NPF_{B8BA4AE2-24D8-46AE-9CCD-271D54F3617F} (Network adapter 'Sun' on local host)
3. rpcap://\Device\NPF_{406CF676-7B6A-4B88-9594-3AF9CCFE0F89} (Network adapter 'Microsoft' on local host)
4. rpcap://\Device\NPF_{7696B504-9E43-44C5-BA89-37C522F29E1F} (Network adapter 'Intel(R) 82579LM Gigabit Network Connection' on local host)
5. rpcap://\Device\NPF_{DCF81245-E6BC-4141-B7C8-7FACEA851B12} (Network adapter 'Microsoft' on local host)

In this example, only one entry corresponds to a real hardware adapter, that is no. 4. That means the following line should be copied into the (youbot_driver)/config/youbot-ethercat.cfg file at the top:

EthernetDevice = \Device\NPF_{7696B504-9E43-44C5-BA89-37C522F29E1F}

Note: this was only an example, on your machine it will surely be a different string.

If you have multiple adapters found which could be correct, just try out one after the other. In the worst case the youbot driver will tell that no EtherCAT slaves were found.
