The lsusb command is not showing one of the attached USB devices with the 4.14 linux kernel. The same hardware works correctly with the 4.9, 4.4, and 3.2 kernels.
The 'missing' USB device is detected, drivers loaded, and works properly. It is only the lsusb command that does not show it. The device is shown using the usb-devices command.
If I enter the
udevadm trigger --subsystem-match=usb
then lsusb shows the missing device. It seems that something has changed in the 4.14 kernel affecting this and I am trying to understand what.
Looking at the output from dmesg, I can see the following differences between the 4.9 and 4.14 kernels.
4.9 kernel:
