Why Do I Need to Unplug and Plug in my USB Device to Keep It Working?

//
I have a year and a half old Dell XPS Desktop running Windows 7 (which is kept updated) that has no PS2 ports. I have a monitor with a built-in USB hub (where the hub has its own power supply). I also have a PS2 keyboard and PS2 trackball, both of which I love and want very much to keep using. When I got this new Dell, I got a PS2-to-USB “Y”-adapter and plugged it into the monitor’s USB hub. Everything worked well for over a year – except that maybe once a week or two, they stopped responding with the computer wake up and I had to unplug and replug the USB plug.

This would solve the problem for another week or two. About a month ago, this issue suddenly became not just a daily problem, but even needed doing every five to ten minutes or so. The power supply to the monitor’s USB hub seems to be fine and the other USB functions seem to work fine as well. I’ve re-routed my PS2 USB cord directly to the computer’s USB port and this solved the five-to-ten minute problem, but I still need to unplug and replug the USB plug every day when I wake the computer up. And yes, I reboot regularly, which has had no effect or improvement on the issue. What do you think?

The problem that you’re experiencing is not uncommon. You tried a couple of things that I would normally recommend, but I can think of a few more that might help you in this scenario.

Why Does the Mouse Pointer Jump around the Screen?

//

My infrared Microsoft Intellimouse is being erratic. Doesn’t follow the direction of the hand movement and lags behind sometimes not moving. I have checked all settings and drivers as much as I know how.

Erratic mouse movement is a pain. You move one way, and the mouse jumps around the screen – often to some other random location.

In most cases the solution to a jumping mouse pointer is actually pretty simple.
