Hey nice video! I have a problem though. There's literally no output, not in minicom, picocom nor using the screen command. The recieve light on the usb is blinking so I'd assume that means it's actually recieving data but none of it is getting displayed. Only thing that get's displayed sometimes is if I connect the recieve pin of the usb to the voltage pin on the pcb, which shows just gibberish. I think I only encountered this in minicom or picocom though, not in screen.
Thanks for your comment. The video is intended to show how to setup a serial connection to a Cubro Network Packet Broker. If you have a Cubro Network Packet Broker and you face challenges to setup a serial connection please contact us at our support portal support.cubro.com.
Greetings. I am executing the command on an Orange Pi, It works perfectly but the configuration is lost after the reboot. Is it possible to configure it so that it remains permanent after each reboot? I appreciate your excellent video.
If using screen to connect, then to disconnect type 'exit' at the prompt. If using minicom, then use CTRL+A to open the exit dialogue, then 'x' to confirm.
And how should I add such a device:( Bus 001 Device 004: ID f000: fff0 Linux 3.4.39 with sunxi_usb_udc RNDIS / Ethernet Gadget ) Unfortunately, I can't connect , on virtualbox
Thanks really a lot for this video. I'm trying to connect a USB/SERIAL cable to the Cisco console cable (serial/rj45) which is connected to the switch Cisco Catalyst 2690. When I run the command lsusb I have the following: MosChip Semiconductor MCS7703 Serial Port Adapter. Then I proceeded to enter the MODPROBE command along with the vendor and product. After I run dmesg | grep MCS7703 I obtain just nothing, but if I enter dmesg | grep tty then I see the following: *usb 2-1: generic converter now attached to ttyUSB0 *generic ttyUSB0: generic converter now disconnected from ttyUSB0 *usb 2-1: generic converter now attached to ttyUSB0 *generic ttyUSB0: generic converter now disconnected from ttyUSB0 *usb 1-1: generic converter now attached to ttyUSB0 After that I run screen /dev/ttyUSB0 9600, BUT I don't see nothing in the console, even I disconnect-connect again my C with the cable plugged in and I don't see nothing. Could you please give me some advice? Thanks in advance!
I do not have any first hand experience with that particular adapter chipset. The only thing I could find when searching online was a rather old blog post where someone was attempting to write a driver for it based on the PL2302 driver (used in this video). Given that, as well as the output from your dmesg command, my best guess is that Linux does not have native support for that particular adapter.
sir , watched your video nice one. want to connect USB SimTech 4g sms modem 7600e series to Centos7 .not able to configure. using smstool3 .pl guide. thanks
The app "Serial USB Terminal" works well for Android. I have used it with the same cables mentioned in the video. You will need the appropriate adapter for you phone to connect the cable (e.g. USB-C to USB-A) play.google.com/store/apps/details?id=de.kai_morich.serial_usb_terminal
Thanks mate! The instructions is well explained and easy to follow
Glad it was useful.
That last command sudo screen /dev/ttyUSB0 115200 didn't work for me. Got sudo: screen: command not found.

Thank you for your video. It was very help.. :-)
How many usbserial can i attach to linux
thanks for the help. after connecting to a device, in my case a Kantronics KPC3+, what is the disconnect command?
If using screen to connect, then to disconnect type 'exit' at the prompt. If using minicom, then use CTRL+A to open the exit dialogue, then 'x' to confirm.
Do these commands work in Ubuntu 22.04?
And how should I add such a device:( Bus 001 Device 004: ID f000: fff0 Linux 3.4.39 with sunxi_usb_udc RNDIS / Ethernet Gadget )

Does not work on Android (Su)

@@cubronetworkvisibility2003 I've tried it. i ended up compling the drivers and using a real terminal
