Macbook Pro – Series 3400 series chipset usb problems?


After a long time… here we go again!

Today a quick post, just a note:

If you bought a MacBook Pro and you would like running Windows 7, it could be possible experiment some chipset problems. In my particular case with USB and bluetooth devices (Wireless Notebook Presenter 8000), and a couple of window-freezed.

Also, in some ocasions Windows threw an error: “Intel 5 Series/3400 Series Chipset Family USB Universal Host Controller – 3B3B (and 3B36) has a driver problem”.

After navigating 10 minutes I just realized that lots of people are experimenting the same trouble, and I would like to show how to solve it in 3 simple steps:

  1. Open your ‘Device Manager’
  2. Show all devices (including hide devices, View menu)
  3. Disable both devices (3B3B & 3B36)

That’s all! :-D

Hope you enjoy this. Leave a comment if this post has been helpfull ;-)

  1. Hi! Since I installed W7 (64 bits) bootcamp on my MBP 6,2 (Mid 2010) a few days a go I notice the warning about the Intel 5 series chipset. But suddenly I started having problems connecting my portable external hard drive connected by firewire. Now it only recognizes my external drive by usb and I think the wireless isn’t so well comparing with other MAC (all under W7).
    Under OS X 10.6.8 all is perfect (firewire and wireless).
    I tried the described solution above but it doesn’t solve my problems!
    Any thoughts?
    Thanks in advance!
