Can't use more than 4 USB devices

I can only use 4 USB Devices on my PC at a time. Whenever I try connecting a fifth device it'll disable one of the other USB devices. Say I connect my drawing tablet, then my USB-headset will stop working. The drawing tablet wont work until I unplug the headset.
The devices seem to disable the same device every time. I have a Wireless Xbox Receiver that'll disable my keyboard if I connect it, and neither of them will work until another device is unplugged.

Motherboard: P8H67-V
8 gigs of RAM
i5 2500K

Any help would be really appreciated.

  1. Are all those USB devices powered devices? The system may have trouble trying to supply enough power to them (maybe a mobo problem? not sureIf it includes things like memory sticks, it probably is a moo problem as that mobo has, I believe 14 usb ports.

    Yeah, they're all powered devices. It sounds like you're right from what you're writing, so does this mean I'll need a better mobo if I'm planning on using more USB devices?
  3. I would've expected that mobo to work, I could of missed it, but I didn't see any limitations on # of powered USB devices.
    May a question to ASUS support will let you know if it's a bad mobo or a limitation of the board.

    Do you have your mobo drivers installed aswell as your chipset drivers?

    I just checked, and apparently I had to download newer drivers. This seemed to fix my problem, thanks!
