Windows Subsystem for Linux supports USB-serial devices.The device must be recognized in Windows Device Manager first.If Windows doesn’t recognize the device, perhaps try the device on a native Linux PC.
This tutorial shows how to set up a USB-over-IP server with Ubuntu 10.04 as well as a USB-over-IP client (also running Ubuntu 10.04). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates 'USB I/O messages' into TCP/IP payloads and transmits them between computers. The most common USB ports and USB flash drives work according to the USB 2 standard. Booting from USB 2 from a live drive is faster than from a corresponding CD/DVD disk. Standard USB 2 flash drives have rather slow flash hardware, with read and write speed much slower than the transfer speed of USB 2, so it is worth checking if the speed is. On Ubuntu WSL, I don't see any logfile update from plugging in the device, which probably means the plug-in event is not being passed from Windows to Ubuntu WSL. Looking at date/time on devices /dev/ttyS. via 'ls -l', there is no time update on the port where the USB device was plugged in. Actually, there is an FTDI chip in the USB device. To identify listening ports on Ubuntu follow the steps below: Use the netstat Command netstat is a command-line tool that can provide information about network connections, including IP addresses, ports and services communicating on these ports.
Configuration
Configure USB-serial adapters in WSL by:
add the WSL username to “dialout” group:
Plug USB-serial adapter into the PC
Look in Windows Device Manager under Ports to see the COM port number.See troubleshooting notes below if it doesn’t show there.
The device must show in Windows Device Manager → USB Devices → Ports.If so, try in WSL terminal, (assuming device is on COM 5 for this example):
Usage
The serial device baud rate must be consistent between device and PC.If the baud rate is incorrect, either no text or garbled text will be seen.For example using 115200 baud:
Connect to serial devices usingPuTTY with WSLviaX11 on WSLor using command line like
Notes
- COM port number can change upon plugging in the same device, especially if replugging into a different physical USB port on the PC.
- If plugging in a different unit of the same type of device, it may likely also get a new COM port number (e.g. two Red Pitayas, even if sequentially plugged into the same USB port, may well get different COM port numbers).
Troubleshooting
If the device doesn’t show up in Device Manager → Ports, see if it was mistakenly enabled as a Mouse or Human Interface Device.If so, unplug and replug your device.
If it still fails to show up as a Port, instead showing up as mouse or HID, try right-clicking and Disabling the device and unplug/plug it once more.
If it still fails, maybe the Windows device driver is missing.Try the device in a native Linux PC and see if the device works there.

Windows 10 Build 16176 (April 2017) added support for USB-serial adapters.
This brief tutorial shows students and new users how to find all ports in use or listening ports when using Ubuntu Linux systems…
Ubuntu Usb.com Port
If you’re a server administrator or webmaster and want to make sure only approved ports are opened on your Ubuntu Linux server, the steps below should come in handy.
Most servers built for public access will have services on them which listen on their assigned ports for communication… In some cases, ports that are not in use will stay open which may lead to them being exploited…
Ubuntu comes with some default commands that can be used to scan your servers for open ports. The steps below will show you how to use some of these commands to identify listening ports and how find them.
Since you can’t have two services listening on the same port, it’s a good chance that you may have ports that you’re probably not using and you’ll want to close them…
Network port is identified by its number, the associated IP address, and the type of the communication protocol such as TCP or UDP.
To identify listening ports on Ubuntu follow the steps below:
Use the netstat Command
netstat is a command-line tool that can provide information about network connections, including IP addresses, ports and services communicating on these ports.
If you don’t already netstat tool installed, use the commands below to install it…
sudo apt install net-tools
If you want to list all ports available on a server, you run the commands below:
sudo netstat -tunlp
For detail command options, view the bullet below:
- -t Show TCP ports.
- -u Show UDP ports.
- -n Show numerical addresses instead of resolving hosts.
- -l Show only listening ports.
- -p Show the PID and name of the listener’s process.
When you run the command above with the options, you should see similar lines as below:
That should give you a lot of information…
However, if you only want to see a specific service name or port, you can use the netstat command with the option above with grep…
Example below shows you to scan for open ports and only list port 22.
sudo netstat -tnlp | grep :22
You should see similar line as below:
The command above using grep shows port 22 only and sshd service is listening on that port…
Use the ss Command
netstat is not install on Ubuntu by default… the ss command is installed as a replacement for netstat. As with netstat, the ss command is use to display network information on Linux systems…
netstat and ss command share almost the same command options… so if you’re use to netstat, ss command should work almost the same.
Computers are crucial in the history of geography and technology. Computers and the computer-led information revolution have changed both scientific practices and many facets of human society in. Wider technology in Geography Creative use of technology combine technology with geography for creative results. Use of technology in geography development. In summary, when integrating the use of digital technologies within our Geography classrooms, it is vital that these technologies are being used for the right reason, with the students’ learning being placed at the center. In other words, the technology should be used to develop and accelerate the students’ learning. Instruments of various kinds were vital for geographical study. The Muslim scientists inherited tools such as the annulus (a circular device for charting the heavens), the quadrant (a quarter-circle-shaped instrument for measuring angles from a vertical reference), and the clepsydra (water clock). This article shares one Geography teacher’s experiences of using computer technology to enhance quality teaching. Introduction Using computers as a teaching tool can be exhilarating one moment and utterly depressing the next.
Cyberlink powerdirector 15 activator crack. To view all listening ports on Ubuntu using the ss command, run the command below:
sudo ss -tunlp
You should see similar screen as shown below:
The output above is similar to the netstat command we ran previously…
Use the lsof Command
The lsof command is another powerful utility available to Linux systems that allows you display networking information.
To list all listening TCP ports using the lsof command, run it with the options below:
Linux Usb Ports
sudo lsof -nP -iTCP -sTCP:LISTEN
Ubuntu Usb Portable
You should see similar lines as shown below:
That should list open ports as well…
Now you know how to list listing ports on Ubuntu, you can use any of the commands above to find ports that are not in use and disable services to them…
