libusb-0.1.so.4 shared lib error in ubuntu 64 bit system

I am trying to install ZTE MF191 driver in ubuntu 12.04 64 bit machine. I am not sure is it support 64 bit or not. But it works fine in 32bit system. These driver package has a executable file named zr When i try to run this it throws an error

libusb-0.1.so.4: cannot open shared object file: No such file or directory

I googled it but can't find a way to install(lib) it. Some people suggested to install 32bit version but i can't find one in synaptic. Please help.

To install the 32-bit version, run:

apt-get install libusb-0.1-4:i386

This only works if MultiArch is enabled (maybe it doesn't if you upgraded from an older Ubuntu version). Look for foreign-architecture i386 in /etc/dpkg/dpkg.cfg.d/multiarch to check if MultiArch is enabled, and if it doesn't, run echo "foreign-architecture i386" | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch to enable MultiArch and apt-get update to get the new package lists.

to install libusb use sudo apt-get install libusb-0.1-4

It failed for me even after sudo apt-get install libusb-0.1-4:i386/sudo apt-get install libusb-0.1-4.

So I did sudo apt-get install libusb-dev instead, and it worked fine on my Ubuntu 64-bit system.

This error still exists in Ubuntu 18.04 LTS; my workaround was to install libusb-dev. This resolved it for me.
