Those of you who have been having trouble with the Steam Controller when in wired mode may appreciated the latest Steam client beta, as it fixes it.
See the full patch notes here.
I had a few people email me about this issue, so it's nice to see a prompt fix.
They still haven't fixed the issue of the Steam Controller not working in wireless mode unless Steam is open (it did originally), so hopefully they will get to that eventually.
