I've been searching pretty furiously for the answer to this question, but to no avail. (distro is Fedora 11 btw)
When I log onto my Gnome session, about 30% of the time my mouse doesn't work. If I unplug it and plug it back in, it works again, but needless to say, reaching all the way behind my desktop and doing this is not very convenient.
All I think I would need to do is rescan the USB bus to "redetect" the mouse so to speak, but I can't figure out how this is done. Obviously the OS does some sort of command like this when Linux boots, right? Or is USB just all magic?

I just Googled this issue, and it appears that issuing the "lsusb" command will rescan for USB devices. You could create a new desktop icon that, when clicked ... oh, crap. I guess that won't work.
I guess you will have to press Ctrl+Alt+F2, log in as root, and issue the "lsusb" command from there. Then press Ctrl+Alt+F7 (on an up-to-date distribution) to go back to X Windows.
And this might not work, depending on what "lsusb" actually does. A better solution might be to connect your mouse to a better USB port. Test your USB ports -- connect the mouse to different USB ports, see if there's one that doesn't disable your mouse when you log off. And don't attach either your keyboard or your mouse to a peripheral USB extension box.
the command doesn't work, just shows:
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
your mouse, keyboard and screen are controlled by Xorg. I have found in the past that things could break for no reason, such as a single key becoming non-responsive, requiring me to map it explicitly with xmodmap.
