lsusb command not found

I've installed Ubuntu on an external drive and it don't see my USB dongle. I am a complete novice with things Ubuntu.

After doing some digging I found that step 1 was to run lsusb. But that set of instructions doesn't say what to do it lsusb command is not found.

Can I use my Windows Internet to download files, then boot in Ubuntu and copy and install stuff, or is ntfs a problem. And then what command lines to use. Maybe its to big a problem for a beginner and should find another disk from another magazine.

I tried

sudo apt-get install usbutils

and got back

it is still telling me command not found

Solution 1:

Use Ctrl+Alt+T to open terminal and run the following command:

sudo apt-get install usbutils
