How to update the OpenBench Logic Sniffer’s firmware

First you need to download firmware updater software from here:
http://www.gadgetfactory.net/logicsniffer/index.php?n=LogicSniffer.Download

Press the UPDATE and RESET buttons of OpenBench board, release RESET button wait 2 seconds and finally release UPDATE button.

Then follow these steps:

$ tar xvf ols-0308-expert.tgz
$ cd ols-0308/OLS_Upgrader/
$ sudo ./ols-upgrader.sh

Unfortunately I got this error:

ols-fw-update: error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory
Press any key to continue...

I tried to create a symbolic link to x86_64 libusb-0.1.so.4 but got this error:

ols-fw-update: error while loading shared libraries: libusb-0.1.so.4: wrong ELF class: ELFCLASS64
Press any key to continue...

Then I figured out I need to install the libusb for i386:

$ apt-get install libusb-0.1-4:i386

Finally the update worked fine.

The tip to fix the libusb I found here: http://askubuntu.com/questions/311401/libusb-0-1-so-4-shared-lib-error-in-ubuntu-64-bit-system
