如何列出yocto上连接的所有USB设备（打印机）？

Question

I am trying to get a USB printer to work with an embedded system using yocto. I have the cups package added to the yocto image. The lpstat command returns that no default destination is available. I am trying to see if my printer gets listed via lsusb, but lsusb does not seem to be a recognized command. busybox lsusb doesn't work.

Answer 1

Busybox doesn't provide lsusb but usbutils does. As you can see here :

Contains the lsusb utility for inspecting the devices connected to the USB bus.

Also, I invite you to use dmesg to understand what happens with the device.
