We have a problem here with keyboard being disconnected many times/day. If I unplug the USB connector, then plug it in again, this works some of the time, but not always. If re-plugging it in does not work, then if I plug in the keyboard at a different port, it sometimes starts working again, but not always. The front USB ports seem a little stretched out; sometimes wiggling the connector temporarily fixes the problem, but not always. The back USB connectors seem nice & snug, but the problem does also happen when plugged in back there.

Sometimes the keyboard works normally for many days, then this disconnecting problem crops again, seemingly random. I can't identify a specific reason why this starts happening, or stops happening. But it's becoming more frequent now. I am not finding a solution in the forums (or maybe I am not searching with the right terms). I am getting zillions of repetitive error messages, a small sample of which is pasted here below. I had these same kind of messages since several years ago, on a different computer (different processor, mobo, case, mouse, keyboard & all) running an earlier version of my OS (Debian). I get similar messages here in a different computer, different keyboard & mouse, running Debian Squeeze. This computer is running Debian Lenny. It is soon to be retired since I just built a brand-new one, but can't retire it until I migrate a whole lot of files to the new one & do some tweaking & installing various apps. Hope someone here has run across this issue & has found a way to solve it. I can't crawl under the table umpteen times/day to plug in a USB cable. Very frustratiing problem. Sample of error messages is below here. Ideas, suggestions would be greatly appreciated.
