I'm having issue with my USB devices when playing games (Lord of the Rings
Online, Team Fortress 2, etc), and only when playing games. I constantly get
the 'USB device disconnect' sound and then a 'usb device reconnect' sound.
Occasionally I will get a dialog box saying I should use the device in a USB
2.0 slot. All of my USB slots are 2.0 and powered. I have tried using
different slots and different devices, but the behavior remains the same.
Here is my hardware. All drivers are up-to-date.

Vista Home Premium w/ SP1 32-bit
ASUS P5E3 Premium@WiFi (X48 Chipset)
eVGA Geforce 8800 GTS 512
Seagate 2700.11 (RAID 0)
Sound Blaster X-Fi Fatal1ty
Logitech G5 Mouse
Logitech G15 V2 Keyboard
Multimedia card reader
