- If you are using USB to UART converter cables,
- then it will show up as a different device. An easy way to
- find out what it will show up in &man.dmesg.8; is to run
- &man.dmesg.8; without having your device connected, then
- running &man.dmesg.8; again to see what your device is
- listed as:
-
- &prompt.user; dmesg | tail -5
-ums0: 3 buttons and [XYZ] coordinates ID=0
-ugen1.5: <Logitech USB Keyboard> at usbus1
-ukbd0 on uhub3
-ukbd0: <USB Keyboard> on usbus1
-kbd2 at ukbd0
-&prompt.user;dmesg | tail -5
-ukbd0: <USB Keyboard> on usbus1
-kbd2 at ukbd0
-ugen1.4: <Silicon Labs CP2102 USB to UART Bridge Controller>at usbus1
-uslcom0 on uhub3
-uslcom0: <CP2102 USB to UART Bridge Controller> on usbus1

- In the commands above, the first &man.dmesg.8;
- happened before the device was connected. Then we
- connected the usb and the second &man.dmesg.8; was used
- to show the device detected. The | tail -5
- pipe was used to do limit the output to 5 lines. This is
- only a way to ensure that our device is detected, but it
- will not show up in /dev/ as
- uslcom0. USB to UART devices usually
- show up as ttyUX where X is the
- number of device.
-
- To establish a connection through USB to UART, use the
- cu command. For example if the
- device is shown up in /dev/ttyU0:
-
- &prompt.user;cu -l /dev/ttyU0 -s [speed]
-
- Where speed is the baud-rate of
- your device which you can find on your device's website.
- For BeagleBone Black, as an example, this is 115,200.
