When launching either VoidPPC Linux or OSX (Tiger or Leopard) on my Powerbook 5,9, the Dell USB mouse works. It is of model MOCZUL. According to the specifications, it is rated to 5V, 100mA. I'm not sure if this is helpful information.
On the other listed OSes, the mouse emits a blue light. Under MorphOS, there's a very slight occasional flicker of blue light but the mouse never truly works.
I have several of these mice and they all exhibit the same behavior.
