QUESTION
I have am335x related customized board and kernel(4.4.16) source code I configure the FTDI module driver. so after kernel start successfully I attach ftdi converter to usb port and then type lsmod command to check module list
...ANSWER
Answered 2020-Jul-11 at 14:41As you can see in the dmesg output:
[ 5.379690] usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60
Looking that up, e.g. here: https://www.google.com/search?q=usb%20vendor%20id%2010c4
Tells you that it's a "Silicon Labs" USB device, who also make the CP2102.
The log does not identify other devices (ignore the linux kernel root hub). So either you have also a CP2102 attached (and the FTDI is not properly connected) or the device you think is a FTDI based device, is not.
In addition you can identify currently enumerated devices using the lsusb
command.
The automatic loading is usually done by udev
or a similar user space daemon/mechanism. A decent explanation can be found e.g. here: https://lwn.net/Articles/740455/
