Public bug reported:
I have a Microsoft Natural Ergonomic Keyboard 4000 (USB) that randomly
stops working, usually on average of once per day. When it happens, the
following occurs: Whatever key I last pressed suddenly starts repeating
on the screen, and the keyboard no longer responds to my typing. If I
then plug in a PS/2 keyboard, the key that was repeating on the screen
immediately switches from whatever it was to an asterisk (i.e., I start
to see ************ on the screen). If I then start typing on the PS/2
keyboard, it begins to work properly, for the most part. However, the
USB keyboard won't work again until I restart.
This problem occurs in Gutsy, but I had a similar problem with this
keyboard in Edgy and Feisty as well. It seems to be getting worse - for
example, in Edgy the problem would only occur rarely, and when it did,
plugging in a PS/2 keyboard, typing on it, and then removing it would
allow the USB keyboard to work again (without a restart).
It's possible that this affects all USB ports and not just the keyboard
- on Feisty I tried it with a USB mouse once and both the keyboard and
mouse froze; however, the keyboard is normally the only USB device I
have plugged in.
I will attach relevant files in the next post.
Thanks very much for any help you can provide!
