Flight Sim Controllers
USB Power Management

This problem first came to my attention when the Thrustmaster H.O.T.A.S. Cougarwould periodically disconnect from the computer - usually as I worked the rudders during final approach!

Computer Pilot ran an article on this in a 2003 edition. The problem is Windows XP being a little over zealous in it's power management regime.

Click on start :

XP Control Panel

Performance and Maintenance


System Properties

Device Manager

USB Device - right click to "Properties" - then DESELECT "Allow the computer to turn off this device to save power"

Press "OK"
