nothing worked. So, I uninstalled SP2 via add/remove programs and that
fixed
my problem. Bottom line - Vista SP2 causes USB wake problems.

After installing Vista SP2 both my Logitech EX 100 keyboard and mouse

can be
used to wake the computer, but once the logon screen is displayed
they stop
working. After several seconds the Windows hardware disconnection
sound
plays, and then sone time later the connection sound plays. Several
seconds
after this the keyboard and mouse start working again. This can all
take up
to a minute and is very annoying.

I am sure that SP2 is causing this problem as I have removed it using
System
Restore and the problem disappears. After reinstalling SP2 the
problem
reappears. Reinstalling drivers for the hardware does not solve the
poroblem.

If I connect the wireless reciever to a USB port on a PCI card as
opposed to
ones on the mother board the problem does not occour, however this is
not
convenient as the keyboard is not recognised when the computer starts
and so
Windows will not load.

I have also posted this problem on the Vista SP2 release notes page.

I had a similar problem. Upon waking the machine, I heard two
'disconnect' sounds then the USB keyboard and USB mouse didn't work. I
hadn't installed anything recently, was just a normal day in the office.

To resolve (worked for me):

Disconnect both devices.
Reconnect into different USB ports.
Connect sound should play.
If only the mouse works, use on screen keyboard to enter password.
After a while the keyboard started working too.
