Hey, I'm the guy that commented on your youtube video yesterday. I've
installed the switcher controller but it doesn't seem to want to
connect to the switcher itself. When I run it via the command line it
gives me this output:

Exception in thread Thread-1:

When I open preferences it shows the switcher is there but when I
press connect I get this:

Connection settings changed

I'm using Ubuntu on a Dell Inspiron-5558 if that matters.
Thanks in advance for the help

Hello Ben,

It's fairly obvious that you have a permissions problem at the libusb
level. You'll probably be able to confirm this by sudo running this.

happy openswitcher user
