Keyboard and mouse disconnect after sleep mode

We've been having the following problem lately with our mini: We'll be away from the computer long enough for it to go into sleep mode. But when we wake it, we'll get the screen back and see the mouse pointer on screen, but the mouse will not work and we can't get the keyboard to input anything. There is power getting to the mouse and keyboard, but none of the input is registering.

The "solution" so far has been to do a hard reboot, which fixes everything, at least until the next time it happens. This doesn't happen every time we wake the computer from sleep mode, either.

For reference: We are using the Gateway keyboard and optical mouse that came with the computer which the mini replaced. And both of these are plugged into a USB hub, and the hub is plugged into the mini. (So I realize this could be a problem with the hub.)

Thanks!

Try plugging the keyboard directly into the Mini and the mouse directly into the keyboard (if possible) and see if this makes a difference.

Can you try a different keyboard and mouse and see if this makes a difference?

LucysDad...

Is the hub self-powered (with a transformer to plug in) or buss powered? Buss powered units are no good IMHO. Must have powered ones, when it comes to hubs.

What brand? Port Authority seems to be tops in my book. I don't know whatever happened to Belkin but they went sour for Mac use in or around 2000. Something happened to Belkin's "suspend and resume" function circuits that affects as what we refer to as sleep and wake up mode. Other 3rd party hubs are a toss up so I don't even go there any more.

The hub is self-powered, and sure enough it's a Belkin. Hmm.

I'd try plugging keyboard and/or mouse in directly, except there aren't enough ports to go around.

It might be worth just giving it a try anyway. That way we can rule out whether or not it is definitely a USB hub problem - I'd say it would be.

I have an Apple keyboard and a USB logitech trackball, and the same thing happens to me. it started perhaps a month ago. My trackball is plugged into the keyboard, and the keyboard was plugged into a hub, so I moved it to the mini, and the problem did not go away. but I turned fast user switching back on (some recent upgrade must have turned it off), and it seems to have gone away.

Everyone,

Try looking at this Thread I started a few days ago:
