I was one of those X52'rs that had to keep calibrating..

Waaaaay too often.... Then I found a thread about Power management of USB hubs and don't ya know I haven't Calibrated my X52 Since... hmmmmmmmm

Start menu
Settings--
Control panel--
System--
"Hardware tab"--
Device manager--
(clik the +) for "USB Controllers"--
Right clik "USB Root hub"--
"Properties"--
under Power management tab...
UNCHECK the "allow the computer to turn off this device to save power"
Do this for any of the USB Root hub that might be in your system (I have two)
I'll bet ya won't have any more issues with "recalibrating"
......and the Powered USB is still a good idea
