    My Logitech MX518 mouse disconnects and reconnects frequently (the device disconnect/reconnect Windows sounds play). When this happens, the mouse stops working for about 2 seconds. When it was plugged into the back of my motherboard, Logitech's SetPoint software would lose track of my settings until I opened and closed the SetPoint window. Now that I've been running the mouse plugged into a front USB port, I don't lose the settings, but the 2 second drop-outs are still very annoying (especially for gaming).

    As for my Steelsound 5Hv2 USB headset, while playing Battlefield: Bad Company 2, I get infrequent "lag outs" that cause the microphone to stop working with either Steam voice chat or xfire voice chat. To get it working again, I have to exit the game/chat and restart xfire. By "lag outs", I mean the game will start running at less than 1fps, the audio gets so choppy you can't understand anything, and then maybe 20 seconds later it goes back to normal—aside from the microphone no longer working in whatever voice chat I was using.

    System specs:

    OS: Windows 7 x64 SP1
    Mobo: ASUS M4A79XTD EVO AM3 790X ATX
    CPU: AMD Phenom II X2 550 Black Edition Callisto 3.1GHz (unlocked to 4 cores)
    RAM: G.SKILL Ripjaws Series 4GB (2 x 2GB) DDR3 1600
    Video: EVGA 01G-P3-N959-TR GeForce 9500 GT 1GB
    PSU: CORSAIR CMPSU-750TX 750W
    HDD: WD1001FALS 1TB

    No overclocking.

    This is a form of overclocking

    Unlocking cores ≠ increasing clock rate.

    Verify in your Power Options the devices are set to never be powered off to conserve energy.

    Did you try another mouse in the same usb port, I bet it's the 518 that's faulty. If another mouse works fine then end of problem.

    I'm an idiot didn't read the headset bit :eek:

    What else do you have plugged in to the same hub? Each port on the computer does not represent a separate hub. The bandwidth on each hub is shared between the devices plugged in to it, and it default to the lowest speed of items attached to that hub. So, if you have a 1.1 device in a 2.0 hub, every device on that hub will run at 1.1 speeds. If you have a USB 3.0 device plugged into a USB 3.0 port, but also have a 1.1 or 2.0 device in the same hub, it wil only run at the 1.1/2.0 speed (also if you connect a USB 3.0 device using a USB 2.0 cable, it will run at best 2.0 speeds).

    USB 2.0 isn't bidirectional, meaning if you have multiple devices in the same hub, each sending and receiving data, you can set up terrible latencies! In the device manager (I assume you know where to go), click on 'Universal Serial Bus Controllers' and double click on each hub. If you click on the power tab it will show you what is connected through that hub. Also check to make sure there are no yellow exclamation marks next to anything!

    Nope, you're not an idiot, you're a winner! I think I'm dealing with two separate problems here, because I've confirmed that the mouse is faulty. If I wiggle the mouse cord where it goes into the mouse, the USB connection drops and comes back. So it's a bad connection with the cord. I'm getting it RMA'ed, so that solves that problem.

    As for the lag out/stuttering in BC2 and loss of microphone signal afterward... I'm still stumped. I'll try the suggestion to lock the extra cores and see if the problem goes away. Just FYI, though, I've been running this system as-is for about a year and a half and this problem has only been happening with BC2, which I installed about 2 weeks ago, so I'm not entirely convinced that those extra cores have suddenly begun causing me problems after all this time without issue.

    Also, to burfadel, none of my hubs have more than one or two devices attached, and all devices are USB2.0; no yellow marks anywhere.
