2020-06-07 | wwan: T2529: harden device completion helper | Christian Poessinger | |
Commit 1c7d7cbd39 ("wwan: T2529: migrate device from ttyUSB to usbXbY.YpZ.Z") added a new completion helper path for USB based serial interfaces. If no USB based serial port was available on the system this produced the following error: "ls: cannot access '/dev/serial/by-bus': No such file or directory" Only list USB based serial interfaces if there is at least one connected to the system. | |||

During testing it was discovered that there is a well known problem (we had for ethernet interfaces) also in the serial port world. They will be enumerated and mapped to /dev/ttyUSBxxx differently from boot to boot. This is especially painful on my development APU4 board which also has a Sierra Wireless MC7710 LTE module installed. The serial port will toggle between ttyUSB2 and ttyUSB5 depending on the amount of serial port extenders attached (FT4232H). The shipped udev rule (/usr/lib/udev/rules.d/60-serial.rules) partly solves this by enumerating the devices into /dev/serial/by-id folder with their name and serial number - it's a very good idea but I've found that not all of the FT4232H dongles have a serial number programmed - this leads to the situation that when you plug in two cables with both having serial number 0 - only one device symlink will appear - the previous one is always overwritten by the latter one. Derive /usr/lib/udev/rules.d/60-serial.rules and create a /dev/serial/by-bus directory and group devices by attached USB root port. vyos@vyos:~$ find /dev/serial/by-bus/ -name usb* -exec basename {} \; | sort usb0b1.3p1.0 usb0b1.3p1.2 usb0b1.3p1.3 usb0b2.4p1.0 usb0b2.4p1.1 usb0b2.4p1.2 usb0b2.4p1.3 So we have USB root 0 with bus 1.3 and port 1.0. The enumeration is constant accross reboots. | |||
