I have a Logitech MX1000 wireless mouse which has a usb receiver. When I
boot my Toshiba Satellite up with the mouse plugged in, everything works
just dandy. Exactly like things should be.

The problem comes when I plug the mouse in after the system has booted.
Once I plug the mouse in I get the following kernel message repeated way
too many times:

[4348319.623000] hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable
is bad?

I know the cable isn't bad because the mouse works in ubuntu if plugged
in before booting, and it works in gentoo and windows on the same
computer. It also works in slackware on a different computer.

My laptop has both usb 2.0 and 1.1 ports (2 of each), and I have tried
using the mouse in all of them unsuccessfully.

I think this may have something to do with ehci/uhci, but I'm not sure.
To test that theory, I tried blacklisting ehci_hcd in
/ect/modprobe.d/blacklist with the line 'blacklist ehci_hcd', but the
module still loaded upon reboot.

Hotplug does work however, for my usb memory stick.

My roommate has the exact same mouse on a different computer also
running dapper, and he has no problems what so ever.

I realize this is a bit vague, but I was led to believe that this may be
a bug from a few people in the ubuntu IRC channels.  If there's anything
else that I can provide to help out, please let me know.
