When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Common USB Device errors are ‘ usb port not working ‘, ‘device descriptor request failed error’ or ‘bugcodeusbdriver’ issues. Simultaneous IP over USB and Ethernet Port? SEGGER - Oliver - Aug 25th 2020, 2:00pm. Subjects regarding emWin, our GUI software Threads 2,119. Garmin Support Center is where you will find answers to frequently asked questions and resources to help with all of your Garmin products. These devices need to be paired with a Bluetooth host, there might be a set up option for a volume limit (if these devices are handed to kids) and other features that are hard to set up this way. With SEGGER's IP-over-USB technology, that is very easy and intuitive. Anybody can do it, quickly, and a manual is no longer required. Disabling the Mass Storage Device functionality¶ Due to a known issue in Segger’s J-Link firmware, depending on your operating system and version you might experience data corruption or drops if you use the USB CDC ACM Serial Port with packets larger than 64 bytes. This has been observed on both GNU/Linux and macOS (OS X).

Communication Device Class - Abstract Control Model (CDC-ACM)This USB class is usually used for serial port emulation and as a modem interface.The class is also often used in combination with older software which previously used RS-232 to communicate with an external device.

• 1Accessing CDC

Accessing CDC on Linux

On Linux no drivers are needed, the device should show up as/dev/ttyACM0 or similar. 'sudo screen /dev/ttyACM0 115200'can be used to access the device.

Accessing CDC on Windows

On Windows 8.1 and below the 'usbser' driver is not automaticallyassigned to the CDC-ACM device. An .inf file for the CDC-ACM device must be installed on these older systems. The device can be accessed via COM portemulation programs e.g. PuTTY.

Accessing CDC on macOS

On macOS no drivers are needed, the device should show up as/dev/tty.usbmodem13245678 or similar. The 'screen' terminalprogram can be used to access the device.

Windows 10 comes with a re-designed driver for CDC-ACM. At the time of writing (June 2019) Windows 10 has an issue with large IN CDC transfers. Sometimes packets seems to disappear inside the Windows 10 USB stack.

The only workaround is to read in small chunks. Or to add a delay to the transfers.We have analysed this using a hardware USB analyser and a test program whichreads data from the device. The device (USB high-speed) sends out data continuously in 512 bytes packets. Each packet has a unique, consecutive ID.The test application checks that the received packet always has the ID of the previous packet + 1. After a couple dozen packet the error usually appears and a packet ends up missing.When comparing the packets which are seen 'on the wire' using the USB analyser with the packets which the Windows 10 program received it can be seen that sometimes packets are missing even though they were clearly successfully received by Windows 10. E.g. on the analyser one can see packets 30, 31, 32, 33 and on Windows 10 one can see 30, 31, 33. It would appear that the method through which data is read from the COM port (Windows API ReadFile, ReadFile overlapped or ReadFileEx) has no effect on the missing packets.

When using the same program on Windows 7 no issues can be seen.

FIND is a free to use protocol for Embedded devices which makes it easy and fast to locate them in the LAN. FIND locates all embedded devices supporting discovery in fractions of a second. With less than 300 bytes of ROM and no RAM for the implementation, it can be easily implemented on any device with any TCP/IP stack. You are free to use FIND for anything, even commercial and closed source software.

FIND - Fast Interoperable Network Discovery Protocol

In today's networks, even simple questions regarding the reachability of a device are nearly impossible to answer. Especially headless devices like sensors, network printers and network attached storages are often not responsive.

New devices which have to request an IP address from a DHCP server to get reachable are an everyday scenario. In home networks the IP address will normally automatically assigned to each device which sends a request. Thereafter, the device is available on the network, but still not automatically reachable for the user. To connect to the new device you need at least its IP address or the device name if local name resolution protocols like NetBios or mDNS are supported. If the IP address and the device name are unknown, the simplest solution is often to check the administration panel of the router and search the list of distributed IP addresses. This is doable, but not user-friendly.

How easy could it be, if every device would simply send a response, if the user asks for the name and the IP address of each device in his network? Sounds simple and reasonable, but nevertheless it is not normal in today's networks.

SEGGER's FIND (Fast Interoperable Network Discovery) protocol is designed to fill this gap. It helps to collect the most important information of each target on the network, works on top of each TCP/IP stack and helps to satisfy the needs of the normal user.

The simplest way to display the collected information is our free tool FIND Discover. It sends queries and lists all valid responses of the devices in the network.

FIND command-line server

To test FIND in your network, you can download a simple command line implementation of a FIND server, which generates and sends valid FIND responses with the information of your host. The application opens the UDP port 50022 and waits until it receives a valid FIND query. A FIND response will be send back after the receipt of a FIND query.

Download Sample command-line FIND server for Microsoft Windows hosts.

The protocol can be used on every hardware and with every TCP/IP stack.
If your device can send UDP packets, it can also add support for the FIND protocol.

Client side:

• Open UDP port 50022 in listening mode.
• Send a response to UDP port 50022 back to the query sender (unicast)

Host side:

• Open UDP port 50022 in listening mode.
• Send a FIND query (UDP broadcast to port 50022) with payload FINDReq=1;.
• Check for responses sent by the devices with FIND support in the network.

emNet client side implementation

The code is for the client side is really simple. The sample implementation uses the emNet UDP zero-copy API.

Add it to your emNet application: Download the archive and add the included files to your project. To enable FIND support on your device, IP_FIND_Init() has to be called in your application. That's it. Thereafter your device will answer FIND queries and can be found in your network.
