Actually try downloading a developer tool called USB Prober and check to see if the mouse is actually being detected on that usb port.
http://developer.apple.com/hardwaredrivers/download/usbdebug.html
if it is then there may be a driver issue in the kernel, check to see if that vendor has a driver for that product on mac. If you are lucky they might be using a standard USB interface chip, from FTDI here: http://www.ftdichip.com/ or Prolific here: http://www.prolific.com.tw/eng/download.asp
Those options are your best chance if the hardware works and the system does not integrate with it.
You could also be using an under voltage USB port so try another port.
Could you post details about the product you are connecting I could help a little more if I knew the brand and model.

emanuelcds have you tried doing what I described in the post above?
USB Prober will tell you a lot about the devices connected to your computer. With that information I could assist you a little better. What make and model# is the mouse? Are you using it through and adapter for example PS/2 to USB?

Have you tried running disk utility from your OSX install disk?
What brand of mouse and model? What data is USB prober listing?
If you run console can you see any errors reported by the mouse or any other program running?

Is this mouse connected to an external hub or is the hub listed the root hub in the Mac Pro?

If you have your mouse plugged into an external hub plug it into the USB port on the front of your mac and see if it works there.
I have had issues with pointing devices being connected through external hubs before.
There could be a conflict if you look at "Port 2: (*dev)->DeviceRequest err: 0xe000404f " which seems to be a under the BRC2070 chip, controlling Bluetooth. I would expect that to only affect the Bluetooth system.
Have you already tried disconnecting USB devices one by one to see if there is a conflict? Your device might be getting less power than required through the USB port it is connected to. This can be corrected by plugging it into one of the ports in the back of your system.
