If i insmod the uhci driver he didn't recognize my USB mouse. But if i did the following:
rmmod uhci_hcd insmod ehci-hcd.ko rmmod ehci_hcd insmod uhci-hcd.ko
the uhci driver it works fine. I'm not sure but it seems to be a bug of the uhci driver.

You either a BIOS or PCI problem as you are getting no interups for USB. You could try a BIOS update or check earlier in your logs for information from the PCI system. If you need more helptry the linux-kernel list.

Hello List,
today i've upgraded to Linux Kernel 2.6.5 from 2.6.0 (using Debian 3.0).
Everything works fine, except my USB mouse. The usb controller didn't recognize the mouse.
