I upgraded to Windows 7 64 bit a couple of months ago. At the same time I installed a WD 1TB SATA II, and WD VRap 150 GB, SATA. I re-installed my USB CH Flight Sim Yoke and Pro Pedals by simply plugging them in and booting up. They loaded and have worked perfectly ever since, retaining all calibrating and sensitivity settings – except for one thing. At times they just lose their connection. This occurs at random times and never while in use. To repair I shut down and switch USB ports and boot up again. Here is what I have done in an attempt to fix this problem: Checked Device Manager. This shows all USB devices working properly.In W7 Control Panel is shows all HID-Compliant Gamed Controllers working properly. The BIOS shows all USB functions [Enabled] USB 2.0 Controller [Enabled], USB 2.0 Controller Mode [HiSpeed], BIOS EHCI Hand-off [Enabled] and Legacy USB Support [Auto].When I get the disconnect , I can swap any of the 8 ports in any manner and the problem still occurs but ONLY to the CH Controls. Every time every thing else plugged in continues to work properly.Went to Control Panel> Power Options. There I have tried all combinations of Turn off display from 15 min to Never. Put computer to sleep from 15 min to never. In the advanced I have changed USB selective suspend settings from Enabled to disabled and back. All combinations. Some times certain combinations will delay the disconnect for a couple of days but eventually it happens.I don’t mind stopping and reconnecting however I fear that I am wearing out the USB plugs and I will have to eventually replace the controls just because of this.

Have you been into Device manager and right clicked on the USB Root Hub Properties Power Management untick Allow computer to turn off this device to save power? There was some discussion on the CH Hangar Forums re Win 7 and CH products which may be worth a look?RegardsPeterH
