When I use the same command in OpenWrt 19 I get the following output.
I even tried with -v -t -s options, but result is the same. Please help me to get similar output as in OpenWrt 13.
I also added the USB drivers in build under Kernel Module-->USB Support
root@OpenWrt0:~# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 017: ID 1949:03a8 Lab126, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
If your output is different, you're probably still missing modules.
when I installed lsusb on my openwrt it also installed
librt
libusb
Thank you so much. The issue was usbutils not added to the build. I actually added lsusb from base system --> BusyBox--->Cutomize Busy Box option --> Linux System Utilities ---><*>lsub, I disabled this and added it from Utilities --> usbutils and rebuilt the image. Now its working.
