USB mouse crashes and disables all USB ports.

[Frem]

I have this USB mouse that works for a while, then crashes. When it dies, it seems to kill all the USB ports, I can't use a memory stick or anything.

Here is the last part of the dmesg log for the latest crash. I had the USB mouse and a keyboard plugged in. (Though this was my first time with the keyboard, and the mouse has been doing this for quite a while.)

In the log, you can see that the mouse died, and both it and the keyboard stopped responding, so I unplugged them both, then replugged in the mouse.
The keyboard sent two "IRQ INTR_SF lossage" messages because I'm using a PS2-to-USB adapter, and I just have the keyboard plugged into it.

So, yeah. Anyone have any ideas on what is causing this and how to stop it?
