USB mouse stops working, reboot fixes it

[Herkulese]

I have a Memorex USB Optical mouse that has worked fine for years, and continues to, but lately, sometimes, not every time, after the PC goes to sleep, and is wakened, the mouse is just not there, and unplugging and replugging into same or different USB port doesn't correct the problem.

If I reboot the computer it works fine every time, until the PC goes to sleep. When I wake it up, the mouse may work, or it may not.

Any ideas?

Your USB port is not regaining power. Try a powered hub.

Would it not regaining power be an issue of the USB driver, physical motherboard, etc.....?
It didn't do this till recently.

Come to think about it, I did install a USB dongle type wireless adapter, and that is about when this started happening. Could the adapter be using enough power so that the mouse can not start up?

Does the hub just plug into one of the Motherboard USB ports?
If the mouse gets power from the hub, does the USB signal then just pass to the computer?

(1) Come to think about it, I did install a USB dongle type wireless adapter, and that is about when this started happening. Could the adapter be using enough power so that the mouse can not start up?

(1) Yes - there is only so much power available at 5 vdc. Every device adds to the sharing.

(2) Yes. A powered hub plugs into any USB port, and provides independent power to devices connected to it, and it lessens the load on the mobo's USB circuitry. The signal passes directly to the computer and power is no longer an issue.

Thanks for that clear explaination.

So, should I put the wireless adapter on the powered hub, or should I leave that hooked up direct, and move my Mouse and Keyboard to the powered hub?

I also usa a USB flash drive once in a while.

I have my mouse, keyboard, digitizing pad, external DVD burner, label printer and scanner all on a powered hub. My wireless adapter/router is connected to my cable modem, but I have my computers all using hard wire. The wireless is for guests and testing a laptop before travel. Am running three computers, all have powered hubs, and never have a USB problem with any of them.

The USB devices that I have are as follows:

Printer (it has its own power brick)
Keyboard
Mouse
Wireless Adapter Dongle
Flash Drive (intermittent use)
Digital Camera (Intermittent use)

The printer has its own power supply, so no issue there.
I will put the keyboard, mouse, and camera when in use, on the powered hub, leaving only the wireless adapter directly attached.
The flash drive will also go into an on board port, but that is only when I need it, unless I see any issues with that.

I believe that you have solved my issue, and I used to have a powered hub, but have to go look for it. Otherwise I will buy one.

Thanks for the help,
Roger

If the mouse is years old get a new one and see if it works better. Things wear out, so try another mouse to see if it is just the mouse going bad. Most likely it is a bad mouse. From your description, it might also be the dongle using all the power. Might be that certain USB ports have priority when the computer boots and by plugging into a different USB port will give priority to the mouse.
