USB devices suddenly not recognised???

[Guest]

Struggled for weeks with usb devices working one minute then not recognised
the next. Tried everything, microsoft help sites where no use, even
re-formatted and re-installed OS. Today, while feeling the urge to chuck
computer in the bin, i went into device manager and disabled "Standard
Enhanced PCI to USB Host Controller". Lo and behold 3 hours later all USB
devices still working properly. Why?, I have no idea!! But it seems to work.
Anybody else having the same sort of problem might want to give it a try.

Keep smiling, maybe Vista will be better

You found the best and only way to solve most USB problems
Disabling the Host controller and then rebooting will reinstall
the USB controller and in most cases solve the situation.

Disabling the controller won't cause a re-enumeration the next time
the PC boots up. To do that, you'd have to uninstall the controller.
The device is still present in the hardware profile - just disabled.

On the OP's issue, when disabling the Enhanced controller all that
did was disable all USB 2.0 support so now all the devices must go
to Full Speed hubs. (USB1(.1))

i understand what you are saying about uninstalling controller and
rebooting, tried that and problem still remained.
Having usb working at a slightly slower rate is a price i am willing to pay
over having no devices working at all, but thanks for all advice recieved.
