Everybody at linuxquestions.org...

Does anybody know a tool to apt-get or commandline action to see what title of lsusb belongs to witch similar devicename in /dev/tty

Because i am working on my system with multiple USB decives to discover...

Thank you, Greets Wouter van Wegen

PS: It is to use on my Raspberry 4 RPIMOD, with total of 6 USB AVR programmers on 2 hubs attached to it.

If you want to see a picture of my project just ask.

Use the device ID(?).

The first device discovered should be /dev/ttyUSB0. If the devices have different serial numbers you could create a udev rule to always use the same device ID. Otherwise, you just have to determine manually which is which as far as I know. I do not see anything else with a device ID. Look at the output of the dmesg command to see how the programmers are recognized.

Is this an AVR programmer.
