Why do i keep losing connection with my keyboard, mouse, and trackpad?

[danmc00]

Every once in a while I will wake my iMac up and the mouse, keyboard, and trackpad can't be found. The only way I have found to fix this is to reboot. This just started after Lion install. Is anyone else having this problem? I know that batteries in all are good.

If your keyboard, trackpad and mouse can't be found, how are you waking your iMac?

That's a good question. To wake my iMac, I always push the spacebar, so it must be connected for just a second then it isn't. Makes no sense to me!

Shutdown. Pull the plug for 1 min. Plug it back in and do a pRAM reset when it comes up.

NVRAM/PRAM has nothing to do with the OP's issues.

It won't help your situation, but here's how it's done, when appropriate:

It is happening now more than ever. Almost every time I wake computer up. Only way I have found to fix is to hard reboot. Starting to get very annoying!

When I go to my iMac now and try to wake it with the keyboard, mouse, or trackpad it doesn't do anything at all. There is no connection! I can wake up cpu by pushing the power button but can't move the mouse, so the only way I can use is to hard reboot. This is getting very frustrating. I guess I will be making a call to Apple tech support later today.
